Abstract

We consider infinitely long electromagnetic wave guide filled with a ferrite. The wave guide has arbitrary but constant cross-section .WeshowthatMaxwellequationsareequivalenttotheSchro¨dingerequationforsingleelectroninthetwodimensionalquantumdotoftheformDwithaccountoftheRashbaspinorbitinteraction.Thespinorbitconstantisdeterminingbycomponentsofmagneticpermeabilityoftheferrite.Theuppercomponentofelectronspinorfunctioncorrespondstothezthcomponentelectricfield,whilethedowncomponent. We show that Maxwell equations are equivalent to the Schr\"odinger equation for single electron in the two-dimensional quantum dot of the form D with account of the Rashba spin-orbit interaction. The spin-orbit constant is determining by components of magnetic permeability of the ferrite. The upper component of electron spinor function corresponds to the z-th component electric field, while the down component \chi$ related to the z-th component of magnetic field by relation (30).
