A numerical method for tunable filter with weighted coupling

A numerical method for tunable filter with weighted coupling

A new approach based on the finite element-artificial transmitting boundary method was presented and numerical examples are shown for AOTF's with a tapered acoustical directional coupler on a LiNbO/sub 3/.
