Characteristic Basis Functions Method in Feko

This video demonstrates the concept and usage of Characteristic Basis Functions Method in Feko. The CBFM can be seen as a modification of the conventional Method of Moments that reduces the number of unknowns of the problem. The CBFM proves its advantages in problems with many variants of the right-hand side of the linear system. This is the case especially useful for computation of monostatic radar cross section (RCS), where the structure is excited by multiple plane EM waves from different directions.
