Abstract
An unusual aspect of macroscopic electrodynamics of
two-dimensional
mirror-odd conducting structures bound up with the band spin-orbit
coupling Hso=α( p×)• σ
of current carriers (where c is one of two nonequivalent
normals to a given structure) is pointed out. Namely, it is shown
that due to the spin-orbit coupling the presence of the in-plane
magnetic field H0 gives rise to a dependence of the
reflection/transmission amplitudes on the structure orientation
c,
the wave-vector of the incident radiation q, and H0 of
the form q•( c×0). This q- and
H0-odd dependence can be the foundation of the optical way to
determine the value of the spin-orbit coupling α.
