Coupling to the electron Bernstein wave (EBW) via a phased array of waveguides is experimentally investigated in the Madison symmetric torus reversed field pinch (RFP). EBWs promise to provide localized heating and current drive in overdense plasmas such as those in the RFP, provided a technique can be developed to efficiently couple power from an externally launched electromagnetic wave to the...

In this paper, an analysis method for optical wave propagation based on photon model is presented for the characterization of optical wireless communication environment. In contrast to radio waves, optical waves have very short wavelengths, so that material properties become important and often cause diffuse reflections. Channel models including diffuse reflections and absorption effects due to...

We inspect the optical properties of dissipative double-negative metamaterials (DNMM) and find explicit expression for total reflection angle correct Fresnel formulae describing refraction DNMM at oblique incident electromagnetic wave on interface \textit{TE} as well \textit{TM} polarization. The reflectivity transmissivity film embedded in a positive index (PIM) surrounding are presented discu...

Aortic impedance, wave reflection magnitude, and compliance were measured in patients with Marfan's syndrome during diagnostic cardiac catheterization. Impedance and wave reflections were calculated from standard Fourier series analysis of ascending aorta micromanometer pressure and electromagnetic flow records. Compliance was estimated by a method recently proposed that uses the area under the...

We have conducted a series of experiments designed to investigate elastic and electromagnetic (EM) velocity anisotropy associated with a preferentially aligned fracture system on a temperate valley glacier in south-central Alaska, USA. Measurements include a three-dimensional compressional wave (P-wave) seismic reflection survey conducted over a 300m 300m survey patch, with uniform source grid ...

S Jacketing technology using fiber reinforced polymer (FRP) composites is being applied for seismic retrofit and rehabilitation of reinforced concrete (RC) columns designed and constructed under older specifications. In this study, the authors develop an electromagnetic (EM) imaging technology for detecting such damage as voids and debonding between the jacket and the column, which may signific...

In this paper, we study two different Graded Index (GRIN) photonic crystal (PC) structures which are named as structure type I and type II. The PC structures are made of the square rod in an air background. To design a GRIN PC structure the lattice constant has been altered in the direction transverse to propagation. We investigated focusing effect             and waveguiding behavior of electr...

– We generalize the invariant imbedding theory of the wave propagation and derive new invariant imbedding equations for the propagation of arbitrary number of coupled waves of any kind in arbitrarily-inhomogeneous stratified media, where the wave equations are effectively one-dimensional. By doing this, we transform the original boundary value problem of coupled second-order differential equati...

A study of the diffraction an electromagnetic wave on a dielectric coating with diaphragm over infinite waveguide antenna array has been carried out. The metal is located at some distance from surface array. influence geometric dimensions and its grating modulus reflection coefficient incident in waveguides investigated. Dielectric coatings different values constant are considered.
