The proposed OAM waves generator is consisted of a feed antenna, and a partially reflective surface(PRS) loaded with a three-dimensional(3D) spiral phase plate. The 3D spiral phase plate is set on the top side of PRS to provide different phases for plane waves with different directions to generate OAM electromagnetic waves. The most important feature of the proposed OAM waves generator is high gain, smaller divergence angle and simple feeding source, without external complex feed network for array of OAM antenna.

Meanwhile, a large power push ratio is adopted to determine the size of transistors at each stage and a voltage divider circuit is used to maintain the same bias. The proposed method was verified by implementing an MMIC PA utilizing a 0.1 $mu text{mGaAs}$ pHEMT process.

By measuring the electromagnetic energy radiated by different materials, it is pos-sible to distinguish them. However, the brightness temperature (TB) can not be directly used for material classification, and those TB-derived material discriminators are not stable charac-terization parameters. In this article, we analyze the multi-polarization brightness temperature model and propose the equivalent permittivity (EP) to characterize the material infor-mation. This parameter, to some extent, is not affected by inci-dent angle and can be derived by multi-polarization measure-ment. The significant advantage of EP is that it reduces the di-mension of parameters in the model. Therefore, it is conducive to extracting object information based on the MMW radiation model. As an application example, we used EP in this article for object classification. Based on EP, we successfully classified four objects with an accuracy of about 99%. Future applications of our method include liquid analysis and scene monitoring.","PeriodicalId":126964,"journal":{"name":"2022 IEEE MTT-S International Wireless Symposium (IWS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114552654","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}

Accordingly, spectrum resources become scarce. The Orbital Angular Momentum (OAM) has been widely researched in recent years and can be used for communication. OAM is a physical quantity different from electric field strength. Quantum OAM reflects the new physical dimension of OAM. Using quantum OAM for communication, Ultra Narrow Band (UNB) transmission can be realized on the spectrum. In the UNB system with OAM, phase synchronization is the key part. This paper proposes a method to implement the UNB system with phase synchronization.

In order to check the electromagnetic emission to avoid the impact on the surrounding electronic equipment or electronic system, the need of emitter identification arises, especially in the field of electromagnetic compatibility(EMC). This paper proposes a systematic radiation emitter identification approach. This approach divides the radiated emission data of equipment or system into three different kinds of components and the radiated emission data is classified according to the similarity of the three components. Three different kinds of electronic equipment radiation emission data are used to verify the proposed method. The classification accuracy for small samples of radiation emission data is 100%, which confirms the effectiveness of this method.","PeriodicalId":126964,"journal":{"name":"2022 IEEE MTT-S International Wireless Symposium (IWS)","volume":"307 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115935682","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}

Firstly, overlapped metasurface structure is proposed to construct a very miniaturized broadband antenna element with the size of only $0.17lambda_{0}$. Then, the newly designed element is placed with a small distance of about $0.4lambda_{0}$ for implementing $1times 4$ wide-angle scanning phased array. Benefit from the small size of the elements, there are enough space to load decoupling structure for ensuring high isolation. The results show that the array can cover the 5G band from 24.25 to 29.5 GHz with a relative bandwidth of 19.53%, and the isolation between adjacent elements is basically higher than 20dB. Moreover, it can achieve a large scanning range of -61° ~61° in low band and -55°~55° in high band respectively, meanwhile, all the active S parameters can keep lower than -8.4dB for ensuring scanning efficiency.
