Metameterial refraction characteristics within the millimeter-wave range

Phase delays, spectral, orientation, and angular dependences of radiation refraction in metamaterial targets have been experimentally studied within the millimeter-wave range. It has been shown that angular and spectral dependences have a complicate structure, which demonstrated properties typical both for positive and negative refraction indexes. At this, a change of refraction nature occurs in radiation wavelength interval comparable with the sizes of metamaterial structural elements.

Investigation of the longitudinal component of an electron electromagnetic field under condition of the shadowing effect

In this paper we present the method and experimental results of the investigation of a longitudinal component of relativistic electron electromagnetic field in the shadow area of a transversal component. We show experimentally, that in a region, comparable with the formation length area no shadowing effect of the longitudinal component of relativistic electron electromagnetic field appears. This is important for understanding of possibility of the shadowing effect in Smith-Purcell radiation and some other radiation types.
