Graphene-loaded wire medium for tunable broadband subwavelength imaging

In this paper, we demonstrate that a wire medium (WM) slab loaded with graphene sheets enables the enhancement of the near field for subwavelength imaging at terahertz frequencies. The analysis is based on the nonlocal homogenization model for WM with the additional boundary condition at the connection of wires to graphene. The principle of the operation of the proposed lens depends on the enha...

Direct measurement of evanescent wave enhancement inside passive metamaterials.

Electric-field measurements inside a negative-permeability-positive-permittivity metamaterial composed of arrays of split-ring resonators directly show that the theoretically predicted enhancement of evanescent waves in passive materials is physically realizable. To circumvent the extreme sensitivity of this phenomenon to the material parameters, we show how the basic phenomenon occurs under re...

Non-Invasive Determination of Blood Glucose Levels by Optical Waveguide

Objective: Today, there are various non-invasive techniques available for the determination of blood glucose levels. In this study, the level of blood glucose was determined by developing a new device using near-infrared (NIR) wavelength, glass optical waveguide, and the phenomenon of evanescent waves. Materials and Methods: The body's interstitial fluid has made possible the development of ne...

Evanescent Fields Inside a Cut-off Waveguide as Near Fields

Usually, electromagnetic evanescent waves are some kinds of near fields. However, it looks as if the evanescent waves inside a cut-off waveguide had nothing to do with any near field. In this paper, we will show that the evanescent waves inside a cut-off waveguide can also be regarded as the near fields of an aerial array.

Non -propagating Waves and Behavior of Curtainwall-pile Breakwaters

Abstract Usually, evanescent modes or non-propagating waves are produced when a propagating incident wave impinges on an interface between two media or materials such as curtainwall-pile breakwater (CPB) at a subcritical angle and decay with distance from interface. To achieve an effective prediction of hydrodynamic performance of CPB and overcome the problem of underestimation of energy loss, ...
