Investigating multi-polarization GPR wave transmission through thin layers: Implications for vertical fracture characterization

Characterization of superconducting thin lms using mm-wave transmission

We present mm-wave transmission as a complementary technique to characterize the properties of superconducting thin lms, obtaining information on both the real and imaginary part of the dielectric function. Examples are given to illustrate the strength of the technique to measure the response of dielectric materials and strati ed systems. We demonstrate the BCS-behavior of a conventional superc...

Two-scale analysis for very rough thin layers. An explicit characterization of the polarization tensor

We study the behaviour of the steady-state voltage potential in a material composed of a two-dimensional object surrounded by a very rough thin layer and embedded in an ambient medium. The roughness of the layer is described by a quasi ε–periodic function, ε being a small parameter, while the mean thickness of the layer is of magnitude ε, where β ∈ (0, 1). Using the twoscale analysis, we replac...

Optical Transmission Model for Thin Two-dimensional Layers

A simplified simulation method to calculate the transmission and diffraction of oblique incident light through a thin two-dimensional layer is presented. The algorithm, based on a ray-tracing technique, uses the Extended Jones-calculus and neglects diffraction within the layer. The algorithm is applied to an in-plane switching liquid crystal display. The transmission at the display surface and ...

Experimental Studies of Wave Transmission through Single Perforated Sheets and Upright Perforated Wave Filters

Investigating the Polarization Properties of Vertical-Cavity Surface-Emitting Lasers

Vertical-cavity surface-emitting lasers (VCSELs) are a new type of semiconductor laser that have emerged as an economical alternative to conventional edge-emitting lasers. Anisotropies within these lasers, such as birefringence and dichroism, cause their optical output to favor one of two orthogonal linear polarizations; however, other optical outputs such as elliptical polarization and polariz...
