Some Research on Thin Film Acoustic Dispersive Delay Lines in Southern France,
Abstract
Dispersive delay lines using acoustic Love waves in single deposited films on substrates have been developed by researchers at Thomson-CSF in Cagnes-sur-Mer. They appear to be the first to have demonstrated such propagation, and also to have demonstrated practical operating devices for pulse compression using such waves. Frequencies up to 40 MHz and relative bandwidths up to 100% have been achieved. Absolute bandwidths of 100 MHz and higher are anticipated by them in work now underway. Data on insertion loss for such delay lines and on propagation loss in deposited films at high frequencies are available from their experimental results.
