If the package resonant modes right within the operation frequencies range of the enclosed circuit, coupling between the circuit and these resonant cavity modes may disturb circuit operation.
如果该封装波导谐振模恰好位于电路工作频率范围之内，电路与封装谐振模间的耦合将干扰电路的工作。

Modulation depth and coupling efficiency were calculated in the range where LP03 mode are cut-off and LP02 mode are guided.
