    An analysis of the effect of losses in the propagation of pulses on superconducting microstrip lines is presented. It is based on the phenomenological equivalence method (PEM) and the two-fluid model of superconductivity to calculate the propagation characteristics of the superconducting line. For most practical situations, it is shown that these losses do not introduce phase distortion, and the a... View full abstract»

    In this analysis partial finite-element discretization of the Poisson equation is implemented. The governing partial differential equation is thus reduced to a coupled set of ordinary differential equations, which is solved analytically. Formulation of the solution with this technique is more general and versatile than with the method of lines. The method of lines is derived as a special case of t... View full abstract»

    The design of a high-frequency dichroic plate consisting of an electrically thick self-supporting metallic mesh that can be used in a linearly polarized quasi-optical system at high angles of incidence is described. The measured and computed performance of a 2.5-in-aperture mesh is given. This mesh has a 3-dB cutoff frequency of 875 GHz and less than 0.75 dB of transmission loss from 950-1350 GHz ...

    A transmission line matrix (TLM) method for modeling distributed circuits containing nonlinear active elements and structures is demonstrated. The scattering properties of the nonlinear element are expressed in terms of differential equations that are solved by stepwise integration with the time step of the TLM algorithm. A cavity oscillator with an active diode with a finite cutoff frequency has ... View full abstract»
