Abstract

In nonresonant broadband measurements, thin samples do not fill the entire sample holder (a waveguide or coaxial‐line section). In this circumstance, the measured scattering parameters have to be transformed from the calibration plane to the sample end surfaces. Furthermore, it is always attractive to measure the complex permittivity of materials with no prior information of their thickness. This article proposes a simple but powerful method to eliminate the dependency of both the calibration plane and the sample thickness on permittivity measurements of thin nondispersive materials. © 2009 Wiley Periodicals, Inc.

Thus, the lasing wavelength has a lower number of photons available for feedback and energy accumulation. At higher reflectivities, although the energy within the cavity is large,
