NEW INTEGRAL EQUATION APPROACH TRANSMISSION TO THE LINES CHARACTERISATION OF COUPLED J. Thijs, MICROSTRIP P. Luypaert, A. Van de Capelle ABSTRACT An accurate numerical procedure is presented for calculating the normal mode parameters of symmetrical coupled microstrip lines. The Green's function approach leads to a singular integral equation of the first kind which is reduced to an equiva

A UNIFIED CAD BASIS FOR THE FREQUENCY DEPENDENT CHARACTERIZATION OF STRIP, R.H. SLOT AND COPLANAR MIC COMPONENTS Jansen and N.H.L. Koster ABSTRACT A novel, unified and rigorous computational approach to the frequency dependent characterization of thinfilm MIC components is described. It provides an accurate, reliable data basis for the generation of microwave and millimeter-wave CAD circuit model

COMPUTER~IDED DESIGN FOR MICROSTRIP RING RESONATORS A.-M. Khilla* Microstrip ring resonators with arbitrary conductor widths are here discussed. A computer-aided design for microstrip ring resonators, based on a parallel-ring-radial waveguide model, has been carried out. Experimental results from 1 - 12 GHz are shown to be in good agreement with the model. The (n >= accuracy of this mode

EMPIRICAL FORMULAS FOR THE IMPEDANCE AND EFFECTIVE DIELECTRIC CONSTANT OF COVERED MICROSTRIP FOR USE IN THE COMPUTER-AIDED DESIGN OF MICROWAVE INTEGRATED CIRCUITS Steven L. March ABSTRACT Highly accurate and computationally efficient equations are presented for the characteristic impedance and the effective dielectric constant of both single and coupled microstrip with a top cover at a non-infinit

DIELECTRIC WAVEGUIDE WITH A FERRITE LAYER AND PERIODIC METAL STRIPS K. Araki, N. Camilleri and T. Itoh ABSTRACT An analysis of dielectric-ferrite waveguide periodically loaded with metal strips is presented. Nonreciprocity of phase constants caused by the gyrotropic nature of the ferrite makes it possi5le to create nonreciprocal leakage phenomena by means of the metal strips. These phen

THEORY AND OPERATION OF WAVEGUIDE JUNCTION WITH TRANSVERSELY MAGNETIZED SEMICONDUCTOR V.I. Miteva, K.F. Ivanov+) ABSTRACT Excitation of microwaves in a waveguide four-port junction, contain~ng a semiconductor plate, biased with transverse d.c. magnetic field is studied analytically and experimentally in X-band. Coupling occurs between the input and the output of the junction when a Hall field

A FIELD ANALYSIS COAXIAL MAGNETRON Thomas E. Ruden~ FOR - IDENTIFICATION OF THE -- SPURIOUS MODES OF THE -- George E. Dombrowskit ABSTRACT The electromagnetic system of the coaxial magnetron has been analyzed as a concatenation of radial waveguides extending from the cathode through the anode vanes and backwa11 slots into the coaxial cavity. The analysis yields, for an arbitrary frequenc

SLOW WAVE CIRCUITS FOR MINIATURE CROSSED FIELD AMPLIFIERS M.J. Clark * ABSTRACT This paper describes three forms of microwave circuit investigated for application in a miniature crossed field amplifier. All three are suitable for manufacture in the cylindrical geometry required for operation in continuous cathode, re-entrant beam devices, and are intended for forward wave interaction. A s

GLOW DISCHARGE TUBE AS AN AMPLIFIER J. Po1itch, A. Rosenberg, Y. Ben-Arye, J. Fe1steiner. ABSTRACT . The amplification of millimeter electromagnetic wave radiation within the cathode region of a cold cathode glow discharge was correlated with the variations in the current-voltage characteristic of the glow discharge [1]. The transfer of energy from the fast electrons to the electromagneti
