Title :
Bragg scattering of surface waves by a photo-induced array
Author_Institution :

Abstract :
A pattern of spots of light projected on to a semiconductor wafer creates an array of scatterers that can diffract millimetre-wavelength surface waves through 90° in agreement with the expression for Bragg reflection
