For the rectangular waveguide grating slow-wave structure, the dispersion relation was obtained by the eigen-function method. The coupling impedance and the Ohmic loss were derived from the relevant ...

In this paper, the dynamic response of clamped rectangular sandwich tubes with metal foam core under transverse blast loading is analytically and numerically studied. First, based on the theory of the ...

It is attractive to use sheet beam vacuum devices to generate high frequency, high-power microwave radiation. In this paper, we present the numerical and experimental studies of a high-power Ka-band ...
