The proposed time-domain quantum Maxwell solver is useful to study the local nature of quantum information propagation such as virtual photons or near single photon sources. We provide numerical examples associated with two photon interference occurring in a quantum beam splitter, called Hong-Ou-Mandel effect.

Planar antenna, while very attractive because of their low-profile character, have difficulties achieving most of the abovementioned goals. Reflectors, even the toroidal type, have very limited scanning capabilities. The closest antenna type that can get close to meet these goals is the Luneburg lens, widely known for years. The present paper presents a multi-beam antenna concept based on a special variation of the Luneburg lens. The unique features of this concept are the following: 1. Complete coverage of a solid angle with a radius of 60°. 2. Constant separation between adjacent beams. 3.

The tunnel diode, a unique semiconductor device with a negative resistance region, is often used in oscillator and amplifier circuits. However, this work exploits one new property for tunnel diodes, that sets a strong foundation for 5G long-range self-powered IoT nodes. This property is verified by the high sensitivity/low turn-on power and self-voltage-regulating behavior of the tunnel diode-based rectifier over a large range of load variations. Compared to a Schottky diode-based rectifier at 28GHz, the tunnel diode counterpart demonstrates a superior compatibility with the ambient mm-wave energy harvesting challenges and needs.","PeriodicalId":135770,"journal":{"name":"2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131059884","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}
