The system provides a low-cost solution to remotely monitor vibrations of any object. In the RF system, two separate antennas are used for the transmitter and receiver. The receiver works in homodyne mode. A single microwave oscillator is used to transmit continuous wave signal as well as the synchronized local oscillator for the receiver. An opamp base band electronics separate the small receiver output signal from a large dc offset due to homodyne operation. In comparison to other approaches, number of components are minimized.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126920205","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}

As the power is transmitted by electromagnetic induction through air medium, the chances of electromagnetic (EM) radiation will be high in the vicinity of the wireless charger. The effect of this radiation can be harmful to human, based on its strength and frequency. Various standards are implemented to fix the radiation limits in the bearable level. Since different standards follow different principles and fixing different limits, the lack of a common scale creates misconception to the manufactures and researchers. This paper discusses in detail about all the existing standards for the WPT applications and comparing it. As the available devices and technologies are relatively delicate and costly, a simplified EM radiation measurement mechanism is presented in the paper. A 100W electric vehicle charger is tested using the method.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133039836","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}

The system is designed to operate at the ISM of 2.45 GHz. In the proposed design, the transmitting (Tx) and receiving (Rx) sections are constructed with the help of identical planar source/load loop and resonating coils on the same face of the dielectric substrate. The use of planar structure eliminates the limitation of the practical applicability caused by the bulky geometry of the non-planar configurations. Further, to improve the power transfer efficiency of the proposed system, a zero-index MTM slab is placed between the Tx and Rx section. The MTM slab controls the wave directivity of the Tx element according to Snell’s law and improved the coupling between the Tx and Rx section. As a result, the efficiency of the proposed system is improved significantly. To justify the proposed approach, the prototypes are designed and experimentally verified. The experimental result confirms the feasibility of the proposed system.","PeriodicalId":338001,"journal":{"name":"2019 IEEE MTT-S International Microwave and RF Conference (IMARC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131606829","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}

The structure allows an excellent control in terms of both bandwidth and transmission zero positioning.The manufacturing strategies considered in the paper consists in the 3D printing of the slotted ridge with different supports.
