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.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"35 9","pages":"1332-1335"},"PeriodicalIF":3.4,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145078627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simulations demonstrate an increase of over 36% in heating uniformity across different heated samples through diode state control. To validate this method, a microwave heating system is customized to conduct temperature measurements. Good agreement is achieved between simulations and experiments, verifying the validity of this method.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"35 10","pages":"1642-1645"},"PeriodicalIF":3.4,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microwave photonic frequency multiplying and frequency conversion are simultaneously employed to shift the radar and communication signals to the same frequency band concurrently. The radar signal is designed to have a greater power to mask the communication signal, increasing the difficulty of signal interception and thus enhancing security. By employing dechirping at the radar receiver and self-interference cancellation (SIC) at the communication receiver, respectively, the radar function can be implemented and the communication signal can also be correctly demodulated after removing the radar masking. An experiment is performed. A 0.3-GHz bandwidth linearly frequency-modulated (LFM) signal is quadrupled and superimposed with two upconverted 0.5-Gbaud orthogonal frequency-division multiplexing (OFDM) signals. A communication data rate of 2 Gbit/s, a radar ranging measurement error of less than ±0.3 cm, and a radar inverse synthetic aperture radar (ISAR) imaging resolution of <inline-formula> <tex-math>$12.5times 10.2$ </tex-math></inline-formula> cm are achieved.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"35 10","pages":"1646-1649"},"PeriodicalIF":3.4,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of its unique resonant mode, the FCSRR is suitable for the perception of rotational motion. The amplitude of the resonant signal changes as the motor rotor drives the rotation of the FCSRR at 3.34 GHz, which produces an amplitude-modulated signal. Then, the rotation period is double of envelope period. A rotational speed measurement system with FCSRR is investigated based on the above principle. The signal processing circuit of the system converts the microwave envelope signal into digital pulses to sense rotational speed. The test results indicate that the measurement resolution of this system is 0.5 r/s with an average error of 0.44% compared to a commercial speedometer. This system can be used as an alternative to a laser tachometer when ambient visibility is low.","PeriodicalId":73297,"journal":{"name":"IEEE microwave and wireless technology letters","volume":"35 10","pages":"1654-1657"},"PeriodicalIF":3.4,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
