Band structure and slow waves experimental and theoretical characterization in an high frequency 1D phononic crystal

I. Malfanti, A. Taschin, P. Bartolini +2

We present heterodyne detected transient grating (HD-TG) measurements on 1D surface corrugated Phononic Crystal (PC) with characteristic band edge wave vector of $\pi /5$ $\mu$m${}^{-1}$.…
