在FEKO中怎么求涂覆的RCS？

coating

YES... "C:\Program Files\FEKO\doc\UserManual.pdf"....
12.26 CO card
This card specifies a dielectric or magnetic coating of wire segments or triangular surface elements. The coating applies to all calculations following the CO card.
.........
Note that for wire coatings, no surface triangles with the same label are allowed. Likewise for surface coatings, no segments with same label are allowed.
If Dielectric / magnetic surface coating (the electrically thick coating) is used, it must remain consistent for the whole FEKO run. (It cannot be on for one solution and off for the next.) It is, however, allowed to change the thickness and the medium parameters of the coating. 

求解设置和算一般金属材料一样，就是加了几个涂敷材料属性的设置，还有涂敷材料厚度。
