Table 1

The comparison of the FEM-BI and the hybrid shell element-BI. Bistatic RCS of the conducting sphere coated by magnetic material is calculated.

Method	Mesh density (wavelength)	Node number	Element type	Element number	Unknowns
FEM-BI	32 elements	3033	Tetrahedral elements	9132	15167
Hybrid shell element-BI	15 elements	323	Shell elements	642	2249
