A new modification of the quasi-field method for calculation of surface acoustic wave devices, which eliminates the necessity of the only phenomenological parameter, is suggested. The structures of radio-frequency identification tags in the microwave band calculated by the quasi-field method and finite-element method are compared and found to be in almost full agreement. Frequency and time characteristics of tags, including autoand cross-correlation signals of tags used for simultaneous recognition of numerous tags in anti-collision schemes, are calculated.
