To measure the complex permittivity of such a dielectric substance as to be used in a thin-film state, in a film state, or in a small-diameter wire state, which has been hard to use as a measurement specimen up to now.
An (N+1)layer round rod body is made of a substance of an axisymmetric structure comprising a specimen layer of unknown complex permittivity and N layers (air gaps can be included therein) of known complex permittivity. The rod body is put through and fixed in a wave guide tube with through holes provided in its confronting side walls. A propagation characteristic parameter is measured on the guide tube with the rod body put therethrough and fixed therein. The unknown complex permittivity of the specimen layer is derived by applying measurement results on the characteristic parameter to a theoretical expression of the characteristic parameter which is a function of the unknown complex permittivity and theoretically determined by the shapes of the guide tube and of the rod body and by the known complex permittivity of the N layers.
