Features of Magnetotransport and Microwave Response of Two Dimensional Electron Gas in Sign-Alternating Magnetic Field

Sign-alternating magnetic field is of great interest both in terms of magnetotransport of two-dimensional electron gas (2DEG) and microwave response of two-dimensional electron gas. Reasons of such interest are emergence of new trajectories of electron motion and changing the energy spectrum of 2DEG. Magnetic field dependences of resistance of 2DEG in cylindrical shells was investigated with Hall bar being located near region of zero effective magnetic field.
