Rigorous Analysis of Large Scale MMlC Circuit Devices
Abstract
The focus of this research has been on the development of scalable time-dependent solutions of Maxwell equations for the analysis of printed microwave circuits. The planar generalized Yee (PGY) algorithm has been developed which is an explicit scheme based on an unstructured grid with planar symmetry. Implicit finite element schemes have also been investigated. Radiation boundaries are enforced using the newly developed uniaxial perfectly matched layer (UPML). It is shown that the PML can be perfectly matched to a general lossy inhomogeneous media, as well as dispersive nonlinear and anisotropic media providing high levels of absorption. The means of efficiently modeling infinitely periodical geometries using orthogonal and nonorthogonal finite difference time domain (FDTD) methods is also introduce. Finally modeling linear and nonlinear devices within the FDTD and PGY methods using a state variable solution is presented. Examples of a linear amplifier, a nonlinear diode and nonlinear amplifier are presented.
