Abstract :
Theory of wiggler superradiance of electron bunch moving in waveguide under group synchronism condition is presented. It is shown that in the reference frame moving with electrons emission occurs at a quasi cut-off frequency. The theory is based on parabolic equation for description of wave profile evolution. Comparison with experimental results is discussed.
