Abstract
The real part of the shear mechanical impedance has been measured for three smectic liquid crystals using a shear-wave reflection technique. Results at 30 and 450 MHz are considerably lower than those expected for an isotropic, Newtonian fluid, suggesting the existence of viscoelastic relaxation.Keywords
