Abstract :
Absorption and reflection characteristics of a spherical wave incident on a metamaterial absorber are numerically calculated on the basis of the plane-wave expansion technique. The absorbed and reflected field and power distributions on the absorber surface can be rigorously evaluated for a spherical wave radiated from a nearby RF source.
