Surface electromagnetic waves on boundary between lossy dielectric and left-handed material with gain

Galaydych, V.K.; Azarenkov, N.A.; Olefir, V.P.; Sporov, A.E. (Вопросы атомной науки и техники, 2017)

It was studied the properties of surface electromagnetic waves that propagate along the interface between the semi-infinite lossy dielectric medium and the left-handed material with “gain”. It was assumed that both media ...
Surface wave attenuation caused by secondary electron emission

Akimov, Yu.A.; Olefir, V.P. (Вопросы атомной науки и техники, 2005)

This study aims to contribute to the analysis of the mechanisms of surface-wave-energy absorption. The discussion is based on a consideration of emissive processes from dielectric surface, which is in contact with collisional ...
Surface wave control in plasma-metal structures with perpendicular magnetic field

Akimov, Yu.A.; Azarenkov, N.A.; Olefir, V.P. (Вопросы атомной науки и техники, 2005)

The nonlinear interaction of high-frequency potential surface waves at a dense magnetized plasma-metal interface with a low-frequency plasma density modulation is considered in the point of view to control the surface ...
Surface wave plasma source for broad-beam ion and electron production

Azarenkov, N.A.; Bizyukov, A.A.; Gapon, A.V.; Olefir, V.P.; Kashaba, A.Y.; Sereda, K.N.; Tarasov, I.K. (Вопросы атомной науки и техники, 2004)

The new type of multipurpose plasma source based on the surface wave sustained discharge is presented. The plasma in the source is generated by the RF surface wave discharge excited by the antenna system placed inside ...
