Abstract: We examine phenomenon of electromagnetic transparency in semiconductorsuperlattices having various miniband dispersion laws in the presence ofmulti-frequency periodic and non-periodic electric fields. Effects of inducedtransparency and spontaneous generation of static fields are discussed. We paida special attention on a self-induced electromagnetic transparency and itscorrelation to dynamic electron localization. Processes and mechanisms of thetransparency formation, collapse, and stabilization in the presence of externalfields are studied. In particular, we present the numerical results of the timeevolution of the superlattice current in an external biharmonic field showingmain channels of transparency collapse and its partial stabilization in thecase of low electron density superlattices.
