Abstract

The surface plasma wave technique for determining the dielectric constant ∊(ω) and the thickness d of a metal film without a preset expression for ∊(ω) is discussed. Two sets of solutions can be derived at a given frequency. By comparing d determined at another frequency, the correct ∊(ω) and d solution can be determined.
