Abstract
Traditional chokes in high-power microwaves (HPMs) often suffer from electromagnetic resonances and strict shape dependence. A conformal and miniaturized choke incorporating special slot structures is proposed in this letter. The narrow Slot 1 loaded perpendicular to the noncontact gap forms a surface with resonance suppression capabilities. In addition, the introduction of Slot 2 establishes an electromagnetic bandgap (EBG) with high-power handling capabilities, effectively preventing leakage. More importantly, the conformal and miniaturized design schemes of the proposed choke were analyzed and developed. A practical implementation case was evaluated through simulations and experiments, confirming its significant performance. Compared to conventional designs, this choke exhibits significant advantages in adapting complex geometrical configurations of HPM.
