Negative refractive index is introduced in metamaterials whereby the Poynting vector of the
electromagnetic (EM) wave is in opposition to the group velocity, or alternatively, when the …

In this work, it is studied the application in hyperthermia of a microwave focusing device
based on meta-materials. The device consists of a planar array of split-ring resonators …

This work shows a microwave focusing device based on metamaterials which can find
application in hyperthermia of tumors. The device consists of an array of split‐ring …

Experimental results showing “negative refraction” and some kind of “lensing”− in the
microwave-infrared range− are often presented in the literature as undisputable evidence of …

Les matériaux artificiellement structurés que sont les cristaux photoniques sont couramment
utilisés pour leurs propriétés dispersives. Leur constante diélectrique varie périodiquement …

Metamaterials are a topic of much research interest because they have such extraordinary
properties. Such materials are generally difficult and expensive to make and to characterize …

Cellular structured negative index metamaterials in the form of a right triangular prism have
often been tested by observing the refraction of a beam across the prism hypotenuse which …

During recent years, metamaterials, which are engineered structures with unique
electromagnetic properties that can not be observed in natural material, have been …

Refractive Indices of liquid materials of various concentration at different temperatures has
been measured by a simple but innovative method using a LASER beam. The measured …

Optical cloaking consists in hiding from sight an object by properly deviating the light that
comes from it. An optical cloaking device (OCD) is an artifact that hides the object and, at the …
