This paper describes a novel approach to the application of conformal mapping to capacitance evaluation. A particular structure composed of an array of identical lines and located below a conductive plate is studied. Results show the application of c

A novel summation approach in technique (SAT) improving on the usual computation by multiple reflections to find the transient response was presented in a previous paper. This technique leads to accurate answers consisting of relatively few terms. Th

We present a scattering method for measuring the unloaded Q of a prototype microstrip (patch) antenna structure without the need to implement connecting circuitry. The patch antenna is placed on a large reflecting ground plane. Two auxiliary antennas

Electromagnetic fields in homogeneous source-free regions can be decomposed into fields that are TE and TM with respect to a particular reference direction (e.g., the z direction). If transverse sources exist, both TE and TM fields may be excited sim

This paper presents a procedure which can be used to model the input admittance of a probe-fed microstrip antenna using simple circuit components. The values of the components are extracted from experimental data and represent the antenna about any r

A pulse is developed by discharging an initially charged lossless transmission line through a load, as shown. A novel summation variation on the usual computation by multiple reflections of the transient response for a realistically modeled pulse gen

Kottler's (1923) extension of Kirchhoff's diffraction integral to electromagnetic fields yields the copolarized and cross-polarized fields of segmented reflectors. For flat sections, the Maggi-Rubinowicz (1888, 1917) potential can be used to transfor

Important characteristics of optical resonators and beam waveguides can be inferred from simple ray-optical considerations. The ray theory is susceptible to an extremely convenient algebraic formulation from which a formal analogy in terms of electri

Calibration of six-port network analyzer is shown to be equivalent to the determination of four Stokes vectors. Analyzer performance can then be visualized in terms of the Stokes vector representing the unknown, relative to those representing the ana

The perturbation produced in the stability characteristics of an empty curved mirror optical resonator upon insertion of an inhomogeneous focusing medium has been examined in the general case wherein the space between mirrors is only partially occupi
