Abstract

The boundary-value problem for a Dyakonov-Tamm wave guided by a twist defect in a structurally chiral material and propagating along the bisector of the twist defect was formulated. The resulting dispersion equation was numerically solved. Detailed analysis showed that either two or three different Dyakonov-Tamm waves can propagate, depending on the value of the twist angle. These waves have different phase speeds and degrees of localization to the twist-defect interface.
