A light diffraction technique for measuring dielectric constants at microwave frequencies

A light diffraction technique for measuring dielectric constants at microwave frequencies

Light diffraction from spatially periodic temperature variations in a transparent solid is reported. Local microwave heating at the antinodes of a standing wave diffracts light; thus a determination of dielectric constant by measurement of the microwave phase velocity is possible.
