Electrically excited axial shear wave propagation within a piezoelectric continuously twisted structurally chiral medium (PCTSCM) plate is examined. Three different plates with distinct material properties are considered, each plate operating in one of three zones in spatiotemporal space. The excited field in each plate is examined by plotting the local polarization angle, the total shear displacement field amplitude, as well as the total field along the helicoidal axis of the PCTSCM. Although the local vibration ellipse of every individual mode rotates in conformity with the material structure, the total field does not. Individual modes beat with each other to produce distinct field behavior in each plate. As modal wavelengths do not scale in proportion to the helicoidal pitch of any of the three plates, axial propagation behavior turns out to be unique in each plate.
