WebDec 22, 2006 · This is more than 5% faster than the velocity of a Rayleigh wave propagating at the surface of a phononic crystal in which ρA,B and C ijmn A, B are constant along the cylinder axis (i.e., h is infinite), namely 2488 m s −1. This might be related to the effect of the silicon substrate. Download : Download full-size image. Webapproaches used to design 1D photonic crystal cavities[42], we realize SAW cavities by chirping the period of a quasi-1D phononic crystal (PnC), resulting in Q factors of 16,700 in atmospheric conditions and 61,100 at 4 K. Our cavities also have a small mode area A eff = 1.87 λ2, where λ is the wavelength of the SAW on a free surface of
