Metamaterial Design via the Density Method

Design of “new” electromagnetic devices such as antennas, frequency selective surfaces and filters with complex geometry and materials, possibly “new” composites and artificial dielectrics or meta-materials has become a realizable possibility. Some examples for these meta-materials are photonic and electromagnetic band gap materials for optical, millimeter-wave and microwave applications, anisotropic ferrites, ferroelectric ceramics and chiral materials [1-3]. The potential for improved designs and new devices using meta-materials prompt us to develop automated design tools which combine the capability to design for both geometrical and material topology.
