Abstract
The optic impedance Z of a medium for the propagation of electromagnetic waves is deduced from the definition of wave impedance. A new optical parameter Zo called “specific optic impedance” is defined. The temperature dependence of Zo is examined and an exponential relationship between specific optic impedances at two different temperatures has been derived. The validity of the new relationship is established using the published data on ethyl acetate, cyclohexane, benzene, and a binary mixture of polyvinyl pyrrolidone in N,N-dimethyl formamide solutions from the literature.
