Electromagnetic Codes in Complex Geometries

Abstract

The project objective is the development of codes to simulate the interaction of charged particles and the electromagnetic field inside of complex chambers. This project is applicable to simulation of microwave devices. The codes are built around the use of generalized curvilinear coordinate systems based on hexahedral elements that can be made to conform to complex boundary surfaces. The new element in this project is the use of multiple coordinate patches to accommodate discontinuous and cylindrical surfaces. The main accomplishment is the development of techniques to allow integration of the Maxwell equations across coordinate discontinuities. The technique is demonstrated on a solid cylinder of variable cross section. The report also presents grid generation techniques.
