Abstract
The objective of this paper is to explore the possibility to use composites polyester/titanates (M 2+Ti 4+O 32- with $\rm M = Ba^{2+}$, Sr 2+, Ca 2+, Mg 2+) to get a miniature high- frequency components, and the proposal of signal processing allowing to minimize the different errors particular to the temporal spectroscopy in matched line for two spaces (time, frequency), and the establishment of an expression that determines directly the permittivity without having to make the inverse resolution transcendent equations related to the propagation. Analysis of results obtained by this signal processing, confirms the validity of Bottreau's modeling law, in low frequency according to the volume fraction and the spectral viewpoint, which allows to anticipate the composition of materials to be used to reply to electromagnetic predefined characteristics.

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.
