摘要：

A numerical technique, called (modified) Powell method, is used to design radar-absorbing materials (RAM's), made up of several dielectric layers, usually on top of a conducting (ground) plane. The absorption of RF energy is mostly done in the last layer. The others are used to match the wave impedance of the RAM to that of the incidence media for the desired angles of incidence, frequencies, and polarizations. The technique is very flexible, allowing the design of RAM's tailored for specific applications or general use. One important example is the design of RAM's that can maintain a minimum absorption rate from normal to almost grazing incidence, over a specified frequency bandwidth.
