ABSTRACT:
An apparatus for evaluating dielectrically-artisotropic materials comprising a plurality of microwave transmitters with more than two planes of polarization, and a plurality of microwave receivers with differing planes of polarization, wherein each transmitter includes a modulator modulating the transmitted microwave beam, the transmitters and receivers arranged, relative to a workpiece to be measured, so as to cooperate in communication therebetween, and wherein connected to each receiver is a device to identify the received amplitude and phase of a component of the transmitted microwave beam, and wherein connected to each receiver is a processor for analyzing the received signals to take more than two measurements including measuring the principal axes, attenuations and phase shifts of the received microwave beam.
