High power microwave sources and technologies eds.
A method of wirelessly transferring power from a source to a receiver is by means of electromagnetic near fields.
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.
Microwave sources transform the kinetic energy of an electron beam into microwaves through the interaction of the electrons with a periodic slow wave structures sws.
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.

The goal of this dissertation is to design novel metamaterials for high power microwave devices.
The microwave beam can be focused and redirected with relatively high efficiency and with no moving parts.
Metamaterials have been considered part of certain design efforts since 1968 as a potential means of improving antenna performance.
Unfortunately the low directivity and.
We have concluded that mtms have greatly expanded the parameter space for dispersion engineering for beam wave interaction.
For over the last decade the concept of metamaterials has led to new approaches for considering the interaction of radiation with complex structures.
