consisting of two-dimensional upstream and traditional one-dimensional downstream Bragg …

We demonstrate both theoretically and experimentally the possibility of correlating the phase
of a Cherenkov superradiance (SR) pulse to the sharp edge of a current pulse, when …

Within the framework of a quasi-optical approach, the nonlinear theory of relativistic surface-
wave oscillators is developed. By presenting the radiation field as a sum of two counter …

The first operation of a coaxial free-electron maser (FEM) based on two-dimensional (2D)
distributed feedback has been recently observed. Analytical and numerical modeling, as …

The sheet beam vacuum electron device is an attractive choice for generating high-power
high-frequency microwave radiation. A millimeter-wave sheet beam backward wave …

We propose planar relativistic surface-wave oscillators with two-dimensional periodic
gratings. Additional transverse propagating waves emerging on these gratings synchronize …

The first experimental study of a coaxial free-electron maser (FEM) based on two-
dimensional (2D) distributed feedback is presented. A new type of cavity formed with coaxial …

The use of a novel hybrid scheme of a two-mirror Bragg resonator consisting of one-
dimensional 1D and two-dimensional 2D reflectors is suggested for generation of powerful …

Within the quasi-optical approach, we study nonlinear dynamics of co-axial and cylindrical
surface-wave oscillators with two-dimensional periodic gratings. Electromagnetic fields in …

Two-dimensional (2D) surface photonic band-gap (SPBG) structures can be obtained by
providing a shallow corrugation of the inner surface of a waveguide wall. It can be used as a …
