Cherenkov-like radiation from metallic metamaterials

The radiation of slit modes excited by convection electron inside a perfect metal film perforated with one dimensional array of cut-through slit is studied. The radiations of non radiating slit modes are achieved by grating coupler which provides the required momentum shift to them. Numerical simula...

Zusammenfassung:The radiation of slit modes excited by convection electron inside a perfect metal film perforated with one dimensional array of cut-through slit is studied. The radiations of non radiating slit modes are achieved by grating coupler which provides the required momentum shift to them. Numerical simulation shows that the radiation intensity of these momentum shifted slit modes are more than that of Smith-Purcell radiation by more than one order magnitude.
