提出了一种将折叠波导慢波电路与二维光子晶体阵列相结合构成的行波管的设计和模拟性能。数值结果表明，具有光子晶体阵列的FW电路的皮尔斯互作用阻抗与不含PHC阵列的电路的皮尔斯互作用阻抗相似。当电路尺寸相同时，带PHCS的行波管和不带PHCS的行波管的增益、输出功率和效率也是相似的；但带PHCS的行波管可以过滤掉非工作模式，这可能会提高有PHCS屏蔽的电路的稳定性。
The design and simulated performance of a traveling-wave tube (TWT) constructed by combining a folded-waveguide (FW) slow-wave circuit with arrays of 2-D photonic crystals (PhC) are presented. Numerical results reveal that the Pierce interaction impedance of the FW circuit with PhCs is similar to the circuit without PhC arrays. The gain, output power, and efficiency of TWTs with and without PhCs are also similar when the circuit dimensions are identical; however, the TWT with PhCs can filter out nonoperating modes, which may improve the stability of the circuit shielded with PhCs when compared to the same circuit shielded by metal walls.
