Physical Lumped Modelling of Thin-Film MIM Capacitors H. Do Ky * , S. Meszaros, * M. Cuhacl .*, B. Syrett ** Abstract To demonstrate the accuracy and versatility of the physical lumped modelling technique, metal-insulator-metal (MIM) capacitors on 254 µm substrates are studied and characterized. The results will show that the proposed model is capable of representing MIM capacitors, having

DESIGN THEORY FOR MAGNETOSTATIC LINES S V / THEORY OF ONE-PORT WAVE FILTERS AND DELAY MAGNETOSTATIC WAVE RESONATORS Zagriadski ABSTRACT The present paper reports a new unified approach to the design of tunable magnetostatic wave (MSW) filters, delay lines and one-port resonators. This approach is based on the electrodynamic theory of the excitation of surface and volume magnetostatic waves (M

AN EQUIVALENT CIRCUIT FOR THE DESIGN OF E-PLANE METAL-INSERT FILTERS IN MILLIMETER-WAVE APPLICATIONS M. Politi, G.B. Stracca, A. Melloni, G. Macchiarella, G.G. Gentili ABSTRACT An equivalent circuit composed of a shunt inductance between two waveguide sections is proposed for the metal fins of an E-plane metal-insert filter. The parameters of the equivalent circuit have been computed by the mode-m

TWO-DIMENSIONAL MODELING AND SMALL-SIGNAL ANALYSIS OF GaAs MESFETs J.L. Caceres . ,E. Lopez .. and J. Perez . ABSTRACT A simple 2-D physical model for the GaAs MESFET and an efficient numerical scheme for its small-signal analysis are described. Results obtained with our simulator and comparisons with real devices show that the model is realistic and suitable for device CAD and optimi

MODAL ANALYSIS OF CURVED WAVEGUIDES L. Accatino, G. Bertin ABSTRACT A rigorous modal analysis of continuously curved waveguides both below and above cutoff is given. This analysis is a basic tool for modelling discontinuities involving curved waveguides and promises to be particularly valuable In the design of BFNs (Beam Forming Networks). As a typical application the modal scattering matrix of

STEADY STATE OF A SAW STABILIZED BIPOLAR OSCILLATOR OBTAINED BY SOLUTION OF A BOUNDARY VALUE PROBLEM M.Schwab, F.J. Zimmermann, P.Russer, F.X. Kaertner and T.Goeller * Abstract for the self - consistent determination of the steady state solution of oscillators is applied to the simulation of a SAW stabilized bipolar oscillator including transmission lines. The boundary value problem was

INHOMOGENEOUS TWO-DIMENSIONAL MODEL FOR ANALYSIS OF MICROSTRIP DISCONTINUITIES ** Wojciech K. Gwarek * ABSTRACT -------The paper proposes a new approach to two-dimensional modeling of microstrip circuits of arbitrary shapes. A new model was developed to be used for finite- difference time-domain (FD-TD) analysis. Characteristic feature of the new model is its inhomogeneity i.e. dependence of the p

SPECTRAL DOMAIN TECHNIQUE FOR THE ANALYSIS OF 3-D DISCONTINUITIES A. Jostingmeier*, A.S. Omar** ABSTRACT The method described here determines the electromagnetic field inside an inhomogeneously filled cavity coupled to waveguides. The structure consists of an arbitrarily shaped cavity, to which two cylindrical waveguides of arbitrary cross section are coupled. The medium inside the cav
