Abstract

The stiffness of a continuously twisted structurally chiral medium (CTSCM) varies helicoidally about the axis of spirality. The structures of axial propagation modes in a CTSCM having a tetragonal reference symmetry have been investigated in this paper. Salient features relating to the management of the phase and the vibration ellipse have been brought out, and may be of assistance in conceptualizing novel devices with plane-stratified geometries.
