  • Method for determination of optical anisotropy of dielectric material by microwave
    Patent number: 4087746
    Abstract: Disclosed is a method for the determination of the optical anisotropy of a dielectric material such as fibrous glass-reinforced plastic resin, particularly the measurement of the state in which reinforcing fibers present in the dielectric material are oriented, by using a microwave characterized by connecting a fixed quarter-wave plate and a rotary quarter-wave plate to a conventional reflective type microwave measuring device in front of which the dielectric material is disposed, whereby the ratio of amplitude and the phase difference which represent the degree of anisotropy of the dielectric material can be determined.
