    It is my pleasure to welcome you on behalf of URSI to the Electromagnetic Wave Theory Symposium. This is, as you know, the third in the series of symposia on this topic initiated by Commission VI of the International Scientific Radio Union. The subjects chosen for the symposium stem from the discussions held at the last General Assembly in Boulder, CO, USA. The central problem in the theory of sca... View full abstract»

  • Infinite integral transforms in diffraction theory

    Publication Year: 1959, Page(s):7 - 11
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (431 KB)

    It is emphasized that rather flexible general solutions of the scalar wave equation formed by integrating a separable solution over a separation "constant" are of direct application in certain boundary value problems if an appropriate infinite integral transform is available. The theory, on these lines, of the diffraction of a scalar plane wave in turn by a circular cylinder, a sphere, and a parab... View full abstract»

    The problems of the diffraction of scalar waves by a circular aperture in a perfectly soft, and in a perfectly rigid, infinite, planar screen are treated. New integral representations of the solution are presented which have the virtue of automatically satisfying the time-reduced wave equation, the radiation condition and the boundary conditions. The unknown functions appearing in these representa... View full abstract»

    A recent method of the authors is applied to the case of scalar scattering by a perfectly reflecting elliptic cylinder illuminated by waves from a line source parallel to the axis of the cylinder. The surface distribution in the shadow zone is calculated and the "creeping wave" representation for the scattered field in the shadow zone is derived. It is shown that the results are applicable if and ... View full abstract»

    We present an exposition and certain generalizations of recent work on a class of problems in classical electromagnetic theory. Briefly, we indicate the approach as the Fock theory which is a method of obtaining the field induced by an incident electromagnetic wave on, or near, the surface of a good conductor. The surface is restricted to be smooth, convex, and of characteristic dimensions which a... View full abstract»

  • Reduction of the integral equations for high-frequency diffraction by disks and strips

    Publication Year: 1959, Page(s):37 - 42
    Cited by:  Papers (6)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (462 KB)

    The kernels of the integral equations for scalar diffraction by strips and disks are special cases of a kernel connected with the generalized axially symmetrical wave equation. A transformation of this kernel enables the original singular integral equations to be reduced to Fredholm integral equations of the second kind. These can be solved asymptotically at high frequencies. Applications are made... View full abstract»

    The back scattering of short plane-wave harmonic pulses incident on a perfectly conducting sphere is investigated for both near and far fields. The pulse return is expressed in terms of the inverse Laplace transform of the CW back-scattered field. The inverse transform is calculated for the initial part of the pulse return using a Tauberian theorem. The latter part of the pulse return is given exa... View full abstract»

  • Decay exponents and diffraction coefficients for surface waves on surfaces of nonconstant curvature

    Publication Year: 1959, Page(s):52 - 61

    The decay exponents and diffraction coefficients for a cylindrical surface of nonconstant curvature are computed by two methods which yield the same results. The results consist of leading terms which depend upon the curvature of the surface and corrections which depend upon the derivative of the curvature. The leading terms coincide with those found previously. With these corrections, the geometr... View full abstract»

    Experimental results are given for backscattering cross sections of cones, prolate spheroids, and oblate spheroids. A brief resume is given first of the image-plane technique used in measuring cross sections. Calibration data show that for cross sections of the order of spheres of 3-inch diameter the attainable accuracy is better than 0.5 db. Cross-section data for various aspects of the targets a...

    To investigate the influence of variable curvature on the damping of diffracted waves (creeping waves) the integral equation method has been applied to an arbitrary convex cylinder. In addition to the well-known damping factor, depending on the radius of curvature R , a first-order correction term yields an amplitude factor View full abstract»

    The field on the axis behind a funnel-shaped screen with a circular aperture, on which a plane electromagnetic wave is incident along the axis, is computed by means of an approximate method proposed previously by the author for the case of short wavelengths. The deviation from plane-screen diffraction and the dependence on the angle \phi_{0} defining the sha... View full abstract»

    THREE model radar ranges have been constructed to measure the scattering cross-section of models. The first of these is a 10-m \mu sec pulse radar operating at a frequency of 35 kmc. The second, operating at the same frequency, is a CW balanced hybrid T system. The third, at 8.75 kmc, has two modes of operation. In one it o... View full abstract»

    A VERTICAL electric dipole in the plane interface between two semi-infinite homogeneous dielectric media is switched on at t = 0 . The resulting electromagnetic field is determined by a new method based on a new representation of the field of a point source as the superposition of the fields of line sources. The field of a line dipole is found by using, first... View full abstract»

    This paper deals with the diffraction of a plane electromagnetic wave incident on a variable impedance half-plane, at right angles to the edge. The problem is dealt with by a method closely related to separation of variables in parabolic coordinates. A class of solutions of the wave equation is obtained in this manner; the boundary conditions which may then be imposed on the half-plane are investi... View full abstract»

    A new simple operational method for the determination of the diffracted far field for wedges with impedance boundary conditions is presented. The exterior angle of the wedge is 2\pi-\pi/2n , where n is an integer. The excitation may be either an incident plane wave or a line source. The method is described in detail for t...

    Several theorems are derived by using the reaction concept. They apply to single frequency sources of finite extent, and to fields which are finite and continuous on a hypothetical closed surface S whose inside or outside is source-free. 1) The field on the source-free side of S is uniquely determined by the normal component...

    Some theorems on the transmission coefficient from a transmitting to a receiving system will be presented. They can be considered as very general theorems in physics, since they can be applied to fields other than electromagnetic theory, such as wave mechanics and fluid mechanics. In electromagnetics they have been applied to the theory of surface waves and to propagation problems, particularly tr... View full abstract»

    An outline is given of a method of simulating the resolving power of large radio telescopes by a process of synthesis, in which use is made of measurements taken with smaller structures arranged in different configurations. The method has been applied to the construction of some large radio telescopes at Cambridge. View full abstract»

    This paper is concerned with the construction and the experimental test of a stepped zone mirror, whose theory has been previously developed. According to the theory, this mirror is free from spherical aberration for any value of the angular aperture and at the same time is corrected for coma. The only monochromatic aberration which cannot be eliminated is astigmatism. A model of the mirror has be... View full abstract»
