Application Of Metamaterials In Microwave Resonators And Slow Wave Structures Read Online. Metamaterials are generally defined as periodic composite structures that are engi neered to modify the electromagnetic properties of materials especially in order to achieve new physically realizable responses that may not be readily available in na ture. Provided by the use of mng loaded slow wave structures are presented. Request pdf on researchgate high power microwave source with a three dimensional printed metamaterial slow wave structure for over the last decade the concept of metamaterials has led to new.
In this work we simulate the interaction of such a metamaterial sws msws with a high current electron beam using the particle in cell pic code magic and performed cold test using the electromagnetic code hfss eigenmode solver 3 in preparation for experiments. In this paper the metamaterial structures based on the split ring resonator approach for optimization of microwave applicator characteristic are used. The msws comprises periodically alternating oppositely oriented split ring resonators srrs connected to a metal tube where the distance between the rings is much less than a wavelength of the radiation generated.
βbecomes larger as frequency decreases. Recently a new microwave sensing platform is being developed using the concept of metamaterials 12 13. Design of a metamaterial slow wave structure for an o type high power microwave generator sabahattin c.

The key to the application of metamaterial resonators for the synthesis of such. Theory of conventional anode blocks considering the peculiar conditions governing the shms and simplifying the equations related to mo tion of electrons we have developed a simplified theory which reveals that in a shm the only compo.
We propose a meander line resonator which could provide negative permittivity as a promoted structure from wire lattice. Antenna size can be reduced and the field distribution remains the same. Such a resonator works at relatively low frequencies and hence has a.
Metamaterial slow wave structure design for high power microwave generation. We describe a new o type high power microwave oscillator that uses a metamaterial slow wave structure msws supporting waves with negative dispersion. Metamaterials are artificially engineered materials made of sub wavelength resonators that can manipulate the electromagnetic waves in a way causing some exotic electromagnetic properties 14.
