NEC-LIST: Boundary Element Method (BEM) in electromagnetics computation.

To anyone who has used BEM modeling in antennas.
 
There are now many advanced and " expensive " modeling programs for
high frequency (including microwaves) circuits and antennas.
 
Typical codes are MoM (NEC), FEM (Finite Element Method), FDTD (Finite
Difference Time Domain) method, and BEM (Boundary Element
Method). These are commercial programs for modeling of
complicated/intricate problems.
 
Unfortunately, those programs are very expensive and out of reach for
the experimenter. Certain problems, that involve, e.g., loading a
antenna or circuit with dielectrics or ferrites, or modeling the
antenna in the ground, cannot be solved with NEC or similar codes,
based on MoM.
 
I have searched the lierature and suppliers of the BEM code, and found
very few references, which BEM to electromagnetic problems. Also for
the above mentioned problems, there are no analytical solutions.
 
Has anybody had experience with the application of BEM for antenna
modeling ? Any advice would be helpful.
 
Thank you.
