We demonstrate theoretically the possibility of efficient amplification and subsequent recompression of sub-nanosecond (0.25-0.3 ns) microwave superradiant pulses, which underwent preliminary stretching and became frequency-chirped. Similar technique

The concept of Compton-type free-electron lasers (FELs) operating in short wavelength ranges with a high efficiency and power level is currently underway at the IAP RAS (Nizhny Novgorod). This concept is aimed at reducing the energy of a driving rela

We present a theory of cavities with longitudinal slits which allow the external ${Q}$ -factor of modes to be evaluated. We also propose a cavity design with a regular section made of a set of metallic blades separated by slits. 3-D-PIC simulation of
