A method of wirelessly transferring power from a source to a receiver is by means of electromagnetic near fields.
Since the first demonstra tion of negative refractive index using metamaterials.
Metamaterials have been considered part of certain design efforts since 1968 as a potential means of improving antenna performance.

The goal of this dissertation is to design novel metamaterials for high power microwave devices.
Metamaterials mtms can be exploited as new means of high power microwave generation.
Unfortunately the low directivity and.
The microwave beam can be focused and redirected with relatively high efficiency and with no moving parts.
We have concluded that mtms have greatly expanded the parameter space for dispersion engineering for beam wave interaction.
Was used as t he microwave source for the 95 ghz.
Light source of 1632 8 nm is used for excitation of five.
1 because of its small size and ease of integration into many different high frequency circuits microstrip antennas have been quite popular for use at microwave frequencies.
We have demonstrated two operational high power mtm sources one generating 5 mw at s band and the other generating 100 mw in l band.
Recently the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements 0 and 1 which possess.
High power microwave sources and technologies eds.
However practical manifestations of such a device operating at high power densities have proven difficult to achieve due to the resonant nature of metamaterials and the resultant high electric fields which place severe constraints on.
Besides the arbitrarily dual band microwave components ultra wide bandpass filters and other compact microwave devices and antennas 50 54 using lc circuit metamaterials in the early stage we took full advantage of gradient refractive index grin metamaterials to invent high performance lens antennas 55 61.
