High power microwave sources and technologies using metamaterials.
Intellectual ventures metamaterials based system has some distinct advantages.
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.
Press 2004 modern microwave and millimeter wave power electronics eds.
Was used as t he microwave source for the 95 ghz.
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.
Since the first demonstra tion of negative refractive index using metamaterials.
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.
High power microwave sources and technologies eds.
By using metamaterials researchers at duke university s center for metamaterials and integrated plasmonics cmip have discovered a way to wirelessly transmit power over much greater distances.
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.
Metamaterials mtm are artificial periodic structures which support reversed cherenkov radiation and backward wave propagation.
Unfortunately the low directivity and.
The microwave beam can be focused and redirected with relatively high efficiency and with no moving parts.
A method of wirelessly transferring power from a source to a receiver is by means of electromagnetic near fields.
