Low-frequency (ω ≪ Δ(T)) transverse sound in superfluid 3He becomes overdamped at temperatures near Tc. However, at low temperatures (T≲0.3 Tc) the off-resonant coupling to the J=2-, M=±1 modes stabilizes a propagating transverse current mode with a large phase velocity and low damping for frequencies above that of the J=2- mode. A magnetic field with H|q lifts the degeneracy of right- and left-circularly polarized waves giving rise to the analog of circular dichroism and birefringence of electromagnetic waves. These features suggest that transverse waves may be more easily detected in the B-phase than in normal 3He. Below we give a brief summary of results on transverse waves in 3He-B [1].
