    The overall objective of this paper is to demonstrate the ability of the spectral moments method, a new method in electromagnetism, to incorporate absorbing boundary conditions. This demonstration is done successfully with plane pulse propagation in free space, and through a comparison with finite-difference time-domain (FDTD) results. The very good agreement of the results leads to the conclusion... View full abstract»

    The dispersion and attenuation characteristics of conductor-backed coplanar transmission lines with finite-width ground metallizations are studied in the frequency range up to 1 THz. The finite-difference time-domain (FDTD) method is used for analysis. Open boundaries are described by means of Berenger's perfectly matched layer. The results are compared to electrooptic measurements. They show that... View full abstract»

  • Path integral computation of lowest order modes in arbitrary-shaped inhomogeneous waveguides

    A general numerical algorithm for the computation of the fundamental modes and related cutoff wavenumbers in arbitrary shaped inhomogeneous waveguides is presented. The method exploits a generalized Donsker-Kac formula to express the lowest order modes in terms of asymptotic generalized Wiener-Ito integrals, whose computation is carried out by means of Monte Carlo methods. Comparison with known so... View full abstract»

  • Direct extraction of the series equivalent circuit parameters for the small-signal model of SOI MOSFETs

    A new extraction scheme is proposed which allows to determine all the series equivalent circuit elements values from S-parameters measurements at a single bias point in saturation. Exploiting the specific shape of a set of impedance loci, the new scheme uses linear regression techniques to solve the extraction problem. The resulting algorithm is very simple and efficient when compared to optimizer... View full abstract»

    In this work we describe a new family of filter transfer functions called Chained Function (CF) filters that have the property of having a reduced sensitivity to manufacturing errors. The reduction is achieved by controlling the position of the return loss zeros while maintaining a given maximum ripple in the inband response. The formulation is given in detail together with an example of applicati... View full abstract»

  • High-accuracy assigned power excitation for the FDTD technique

    When the finite-difference time-domain (FDTD) technique is used in continuous wave excitation, the control of the effectively excited power is not allowed by classical approaches. In this letter two possible solutions, working also for nonuniform sampling of the computational domain, are proposed and illustrated. Examples of successfully applications for a metallic rectangular waveguide are, final... View full abstract»

  • Mode transitions between bound and leaky regimes in lossy dielectric waveguides: a numerical investigation

    Publication Year: 1997, Page(s):393 - 395

    The authors present a novel numerical study of mode transitions between bound and leaky regimes in a lossy-substrate dielectric rib waveguide. An entire-domain basis Galerkin's method is employed to determine the wavenumbers of the transmission line modes. The obtained results show that as the loss tangent gradually increases from zero to infinity, the plots of the attenuation constants alter betw... View full abstract»

  • Use of an active retrodirective antenna array as a multipath sensor

    Publication Year: 1997, Page(s):399 - 401

    The use of an active retrodirective antenna as an indicator of multipath propagation effects is investigated by the authors. It is shown that the flat azimuthal gain response normally associated with a retrodirective antenna array can be significantly modified by the presence of multipath signals. These signals act as secondary sources impinging on the retrodirective antenna array and give rise to... View full abstract»

  • Approximate upper and lower bounds on the VSWR of a 3-port circulator with nonideal loads

    The upper and lower bounds on the voltage standing wave ratio (VSWR) at port 1 of a 3-port circulator with a complex load under any phase conditions at port 2 and a nonideal termination at port 3 is of some interest in microwave engineering. The purpose of this letter is to give a solution to this problem under some simplifying conditions. The lower bound obtained here is in keeping with the defin... View full abstract»
