Employment of gradient metal-film output mirrors in terahertz discharge lasers [PDF]
Радиофизика и электроника, 2021 Subject and Purpose. The problem of output beam matching with the waveguide transmission line often arises when using terahertz lasers. The special quasi-optical devices that are used to combat the problem lead to radiation losses and additional material

Casimir force between metallic mirrors [PDF]
The European Physical Journal D - Atomic, Molecular and Optical Physics, 2000 We study the influence of finite conductivity of metals on the Casimir effect. We put the emphasis on explicit theoretical evaluations which can help comparing experimental results with theory. The reduction of the Casimir force is evaluated for plane metallic plates. The reduction of the Casimir energy in the same configuration is also calculated.
