摘要
Features of anomalous refraction of low-frequency electromagnetic waves are investigated in all-semiconductor nonmagnetic superlattices with a periodic array of two-dimensional electron gas layers under quantum Hall effect conditions. We show that the structure exhibits negative refraction on the lateral surface for all angles of incidence, in the frequency region which has no limitation from the low-frequency side, and that for such intriguing properties it requires no resonance frequency and no negative component of the permittivity tensor.
