We study the radiation properties in electron waveguide structure with multistep discontinuities and soft wall lateral confinement. Radiation mechanism and conditions are examined by numerical simulation of dispersion relations and transport properties. The study of geometry variations shows its significant impact on the radiation intensity and direction. In particular, the periodic corrugation structure exhibits strong directional radiation. This interesting feature may be useful to design a nanoscale transmitter, a communication device for future nanoscale system. (c) 2007 American Institute of Physics.
