Abstract
An apparatus for evaluating dielectrically-anisotropic materials including a plurality of microwave transmitters with differing planes of polarization, and a plurality of microwave receivers with differing planes of polarization, wherein each transmitter includes a device for modulating the microwave beam to be transmitted, the transmitters and receivers arranged, relative to a workplace to be measured, so as to cooperate in communication therebetween, and wherein connected to each receiver is a processor to identify the received amplitude and phase of a component of the transmitted microwave beam, and to analyze by Fourier analysis the received signals to identify the principal axes, attenuations and phase shifts of the received microwave beam without requiring the phases of the transmitted microwave beams to be synchronized.
