Electromagnetic tunneling through a single-negative slab paired with a double-positive bi-layer [PDF]
, 2011 We show that resonant tunneling of electromagnetic fields can occur through a three-layer structure composed of a single-negative (i.e., either negative-permittivity or negative-permeability) slab paired with bi-layer made of double-positive (i.e ...

Transmission Studies of Left-handed Materials
, 2001 Left-handed materials are studied numerically using an improved version of the transfer-matrix method. The transmission, reflection, the phase of the reflection and the absorption are calculated and compared with experiments for both single split-ring ...

Conductivity and permittivity imaging at 3.0 t [PDF]
Concepts in Magnetic Resonance Part B: Magnetic Resonance Engineering, 2012 AbstractTissue conductivity and permittivity are critical to understanding radio frequency (RF) power deposition during magnetic resonance imaging (MRI). These electrical properties are also important in treatment planning of RF thermotherapy methods (e.g., RF hyperthermia).

Dielectric and polarization experiments in high loss dielectrics: a word of caution
, 2008 The recent quest for improved functional materials like high permittivity dielectrics and/or multiferroics has triggered an intense wave of research. Many materials have been checked for their dielectric permittivity or their polarization state.

Effective Permittivity of a Statistically Inhomogeneous Medium with Strong Permittivity Fluctuations [PDF]
Progress In Electromagnetics Research, 2004 Most previous multiple-scattering theories for electromagnetic waves in strongly fluctuating media are limited by the assumption of statistical homogeneity of media. In the paper, a lossy electrically isotropic random medium is considered whose mean permittivity distribution, as well as the multipoint permittivity's moments are invariant under ...
