BS 7737 1 is an international standard that applies to the procedures for the determination of relative permittivity and dielectric dissipation factor and of quantities related to them, such as the loss index, of dielectric materials in the microwave frequency region (i. e. frequencies above about 300 MHz up to optical frequencies). Unlike the test methods employed at lower
