2D TF/SF Simulation and RCS Detection Introduction

Compatibility:

2D Total Field/Scattering Field (TF/SF) is a special excitation type that excites arbitrary tilting plane wave in the enclosed rectangular surface. Inside the rectangular region, it generates the total field. Outside of this rectangular region, it is the pure scattering field. TF/SF  simulation enable RADAR cross Section analysis. Complex grating layout analysis and other plane wave simulation will benefit from this TF/SF technique.

The following lesson show how TF/SF separate the total field and scattering field in free space and how RCS is detected for an infinite dielectric rod.

Note: The corresponding project file can also be found in the 32bit Sample file folder,
