| Abstract: | In the paper, the computing method and examples of radiation admittances andstatic capacitances for the filters consisting of cutted interdigital transducers(IDT) are given out.The radiation admittances and static capacitances of cutted apodized IDT are almost 1/4 of that ofno cutted apodized IDT. |
