Abstract :
Many electromagnetic applications can be analyzed using a "standard" FDTD code. However, some applications require special features such as ground interaction, periodic boundary conditions and more advanced excitation sources. This paper presents examples of such applications and references are given to work where descriptions of necessary enhancements to the FDTD method can be found. Application examples are given regarding synthetic aperture radar (SAR), large antenna arrays, infinite antenna arrays and waveguide problems.
