Computer Simulation of High-Frequency Electromagnetic Fields

Andrey Grigoriev

A chapter in Computer Simulation from IntechOpen

Abstract: High-frequency and microwave electromagnetic fields are used in billions of various devices and systems. Design of these systems is impossible without detailed analysis of their electromagnetic field. Most of microwave systems are very complex, so analytical solution of the field equations for them is impossible. Therefore, it is necessary to use numerical methods of field simulation. Unfortunately, such complex devices as, for example, modern smartphones cannot be accurately analysed by existing commercial codes. The chapter contains a short review of modern numerical methods for Maxwell's equations solution. Among them, a vector finite element method is the most suitable for simulation of complex devices with hundreds of details of various forms and materials, but electrically not too large. The method is implemented in the computer code radio frequency simulator (RFS). The code has friendly user interface, an advanced mesh generator, efficient solver and post-processor. It solves eigenmode problems, driven waveguide problems, antenna problems, electromagnetic-compatibility problems and others in frequency domain.
