A Modified Lanczos Algorithm for the Computation of Transient Electromagnetic Wavefields - Microwave Theory and Techniques, IEEE Transactions on

چکیده
A new method for computing transient electromagnetic wavefields in inhomogeneous and lossy media is presented. The method utilizes a modified Lanczos scheme, where a socalled reduced model is constructed. A discretization of the time variable is then superfluous. This reduced model represents the transient electromagnetic wavefield on a certain bounded interval in time. Some theoretical aspects of the method are highlighted and numerical results showing the performance of the method for two-dimensional (2-D) configurations are given. Also, comparisons between this Lanczos method and the finitedifference time-domain (FDTD) method are made.

Pole-zero computation in microwave circuits using multipoint Pade approximation - Circuits and Systems I: Fundamental Theory and Applications, IEEE Transactions on
AbstructA new method is proposed for dominant polezero (or pole-residue) analysis of large linear microwave circuits containing both lumped and distributed elements. The method is based on a multipoint Pad6 approximation. It finds a reducedorder rational s-domain transfer function using a data set obtained by solving the circuit at only a few frequency points. We propose two techniques in order...

Computer simulation of general microwave nonlinear circuits excited by a large number of input tones is addressed. The algorithm, based on the spectral-balance method, uses novel index-vector and convolution-matrix generation techniques. That, in conjunction with a new nonlinear-device modeling approach (which directly takes into account the higher order derivatives of the I=V and Q=V character...

In this paper, a simple and computationally low-cost modification of the standard finite-difference time-domain (FDTD) algorithm is presented to reduce numerical dispersion in the algorithm. Both twoand three-dimensional cases are considered. It is shown that the maximum error in phase velocity can be reduced by a factor of 2–7, depending on the shape of the FDTD cell. Although the reduction pr...

This paper investigates a measurement method that characterizes lossy printed multiconductor transmission lines, its accuracy, the choice of measurement representations, and some simple approximations. We illustrate the method with measurements of a pair of lossy coupled asymmetric microstrip lines.

* D Abstract --Lossless broad-band microwave active inductors for generalpurpose use in microwave circuits are proposed and their characteristics are discussed. These active inductors are composed of a common-source cascode FET and a feedback FET, and operate in a wide frequency range with very low series resistance. A maximum Q factor of 65 is obtained. Theoretically, it can reach infinity. Fu...
