Abstract:

When the electrically thin unit cell of a laminated composite material is made of two bianisotropic sheets whose constitutive properties in the thickness direction are decoupled from the constitutive properties in the interfacial planes, the laminated composite material can be homogenized into a material, not all of whose constitutive parameters are independent of each other. This nonindependence of the constitutive dyadics of the constituent materials and the homogenized composite material is captured by two simple constraints, which may not hold if even one of the two constituent materials has more complicated constitutive properties than stated above.

Keywords: bianisotropic composite materials; homogenization; laminated composite materials; magnetoelectric parameters
