Abstract :
The coupling-of-mode (COM) model of the interdigital transducer (IDT) is modeled by deriving and solving the COM equations which considered the voltage and resistance of the IDT finger electrodes. In addition, zero input and zero state solutions are added as the solution of the COM matrix equations. According to the IDT model and the reflectance of the reflector, the surface acoustic wave (SAW) delay line is modeled, and the wireless passive sensor based on SAW delay lines is modeled and simulated. The COM model of the wireless passive sensor can simulate the delay phase variation with the pressure well, and it can be used as an effective tool for designing and analyzing the sensors based on SAW delay lines.
