Abstract :
Experimental observations and theoretical predictions of the reflection of surface acoustic waves by thin (~200 nm) aluminium dots on Y-cut lithium niobate are presented. Reflection of z-propagating waves into the x-direction show marked variations with size and shape for rectangular dots. The variations can be accounted for by electrical effects alone.
