Radiation from a quasi-periodically modulated electron beam is studied using number theory. The quasi-periodic modulation consists of two different sinusoidal signals at frequencies and . An electron beam with such a modulation radiates at a third frequency, . It is shown that the electron radiation is dominated by an interaction among these three frequencies and the radiation frequency may be different from any integral multiple of either modulation frequency.
