Introduction

The great interest in microwave frequencies arises for a variety of reasons. Basic among these is the ever-increasing need for more radio-frequency-spectrum space and the rather unique uses to which microwave frequencies can be applied. In more recent years microwave frequencies have also come into widespread use in communication links, generally referred to as microwave links. The applications of microwaves and microwave technology extend much further, into a variety of areas of basic and applied research, and include a number of diverse practical devices, such as microwave ovens, sensors, and antennas.

Most of the microwave components require a very careful design phase in which the behavior of the electromagnetic field within the entire structure must be predicted in order to avoid undesired effects due to tool tolerances, material imperfections and packaging.

In order to understand how the electromagnetic field behaves within a given electromagnetic structure, a computational aid is indispensable to help engineers understand the field distribution. Even though a number of commercial analysis packages are currently available, they are rather expensive, and the source code is not available. The latter prevents students from understanding the logic behind the simulation.

In this paper we describe an ongoing project being developed at the University of Texas at Brownsville (UTB) that intends to overcome these limitations by implementing, based on a consolidated frequency domain technique, a novel electromagnetic structure simulator using a pre-existent 94-node Beowulf machine.

The merit and innovation of this project is how it integrates disperse tools and techniques into a single coherent framework that can be utilized with minimal effort and high confidence by the community interested in the research, teaching, learning and diffusion of electromagnetic wave simulation and analysis.

The technique used by the simulator is the Finite Elements Method (FEM). Because of its unique features, the FEM is becoming the workhorse for electromagnetic modeling and simulations. Many research and development codes that are now available in universities and industries, have demonstrated the utility and capability of the method.
