“…Embedding of lumped elements (LEs) into 3D field model enlarges the capability of the code, as an LE excludes the necessity of generating very fine mesh inside such parts as resistors, capacitors and inductors. In the RFS code, linear and planar LEs are implemented [17].…”

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.
