Materials for application in millimeter and submillimeter ranges

Properties (complex refractive index, permittivity, transmission and reflection coefficients) of the different materials (liquid and solid dielectrics, semiconductors, ferrites, composite, building, natural and common use materials) at the millimeter and submillimeter wavelengths are presented. These properties are of a great interest for millimeter and submillimeter guiding and antenna systems, including passive and active devices inserted in such systems, for millimeter and submillimeter propagation especially for indoor propagation.
