Abstract

Full wave numerical study of electromagnetic wave reflection from and transmission through an array of thin, perfect conducting, planar strip complex-shaped elements placed on a magnetized ferrite substrate is carried out. Our results show, that the absorption level and the frequency band of the structure, when the ferromagnetic resonance and a metal element resonance are close in frequency, are larger than the corresponding characteristics of the ferrite layer without metal elements. A significant enhancement of the Faraday rotation has frequency shift with respect to the main resonance. Both right-handed and left-handed circular polarized incident waves interact effectively with a metal array placed on ferrite substrate unlike the known resonant interaction when only one kind (right- or left-handed) of circular polarized waves interacts with the ferrite slab without metal elements.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
