I want to create a RF filter with comsol 4.1 but I have some problems about applying ac voltage,i don't know how do that,my device have some electrodes and reflectors on piezoelectric layer i created that and i just applied dc voltage to diffrent electrode and get eigenfrequencies so i have some questions:-if i select piezoelectric interface or acoustic interface?-how can i apply sin voltage with high frequency to my electrode sothat i can see deformed this voltage at the end of device?(because my device is a rf filter)
please help me because i'm realy new at comsol
