UCF College of Engineering and Computer Science<\/a> assistant professors Kenle Chen, Zhaomiao (Walter) Guo and Luigi Perotti have been named 2023 U.S. National Science Foundation (NSF) Faculty Early Career Development program (CAREER) award winners. The combined award total is an estimated $1.5 million.<\/p>\n Recipients of this prestigious, early-faculty award exhibit the potential to serve as academic role models in research and education, and lead advances in the mission of their department or organization.<\/p>\n Each UCF awardee is using their expertise to study the core part of a key system \u2014 whether it\u2019s Perotti understanding heart mechanics<\/a> in relation to health and disease, Guo\u2019s research on harnessing solar power through electric vehicles<\/a> or Chen, who is redefining high-speed connectivity<\/a> used in communication antennas.<\/p>\n Kenle Chen<\/strong><\/p>\n Department of Electrical and Computer Engineering<\/strong><\/p>\n Project Title:<\/strong> Non-Reciprocally Coupled Load-Modulation Platform for Next-Generation High-Power Magnetic-Less Fully Directional Radio Front Ends<\/p>\n Award:<\/strong> $500,000<\/p>\n Our current radio spectrum, or the range of frequencies used for wireless communications, is quickly becoming congested due to rapidly increased user volume from humans and smart devices, as well as from new wireless technologies, such as Wi-Fi7, 5G+ and more.<\/p>\n Assistant Professor Kenle Chen, from the Department of Electrical and Computer Engineering, is developing a first-of-its-kind technology that could alleviate this congestion and allow for more efficient and reliable communications.<\/p>\n In emerging communication systems, an essential device is a circulator that helps control the flow of signals by routing them between an antenna, transmitter and receiver. It can be found on base stations on Earth and on satellites in space.<\/p>\n Traditional circulators rely on \u201cmagnetic material,\u201d in which signals travel in one direction under the influence of a magnetic field.<\/p>\n \u201cI can foresee that this research will be wildly exciting and enable knowledge for the future 6G systems featured as joint communication and radar,\u201d Chen says.<\/p><\/blockquote>\n Recently, microchip-based, non-magnetic circulators have become possible, but their performance is far from their magnetic counterparts. For instance, state-of-the-art non-magnetic circulators can only handle watt-level of transmission power, which is far below the usable range of many realistic systems, Chen says.<\/p>\n Chen\u2019s approach unleashes the high-power operation of a non-magnetic circulator in an indirect way that will enable more than 10 watts of signal transmission and allow bidirectional signal flow at the antenna interface. Making the technology completely magnetic-less renders a more affordable solution for wireless industries, Chen says.<\/p>\n \u201cIt\u2019s a way to directionally route the transmission signal and receive signal, so it’s a bidirectional process, using a single unified antenna,\u201d Chen says. \u201cIt will meanwhile enhance the efficiency of high-power amplifiers, the most energy-consuming unit on all wireless platforms.\u201d<\/p>\n Additionally, current magnetic circulators are quite expensive, large and heavy in size \u2014 leading to high manufacturing and installation costs for the system as well as increased maintenance requirements. Chen\u2019s new technology will shrink the weight and size of the emerging radio system.<\/p>\n The significant advantages of Chen\u2019s disruptive technology have created interest from wireless and semiconductor industries. Chen says that when installing a current antenna array high onto a base station, oftentimes a helicopter or heavy lifting equipment is needed.<\/p>\n \u201cIf we can get rid of magnetic circulators, then we can very much minimize the size and weight of this antenna array,\u201d he says. \u201cSo, workers can just carry it on their back as they install it \u2014 saving the overall cost and improving labor efficiency and safety.\u201d<\/p>\n Chen\u2019s NSF project will establish the theoretical foundation and practical design methodologies for the proposed technology. He will demonstrate the effectiveness of his proposal using prototypes that mimic the advanced antenna array system within an anechoic, or echo-free, chamber at UCF.<\/p>\n Chen will be working with his research group and the UCF INSPIRE Lab. His team will also provide outreach programs to K-12 students with videos and lectures about wireless technology.<\/p>\n Chen earned his doctoral degree in electrical engineering from Purdue University in 2013 and worked in the industry before joining UCF in 2018. He credits the four years he spent in the wireless semiconductor sector for fueling his excitement toward developing new research.<\/p>\n \u201cI can foresee that this research will be wildly exciting and enable knowledge for the future 6G systems featured as joint communication and radar,\u201d Chen says. \u201cBeyond the technological frontiers, it will address the nation\u2019s core interests in spectrum sustainability and ubiquitous coverage of high-speed connectivity and lead to economic benefits in the future.\u201d<\/p>\n Zhaomiao (Walter) Guo<\/strong><\/p>\n Department of Civil, Environmental and Construction Engineering<\/strong><\/p>\n Project Title:<\/strong> A Decentralized Optimization Framework for Next-Gen Transportation and Power Systems with Large-scale Transportation Electrification<\/p>\nNon-Magnetic Technology for the Future of Communications<\/h2>\n
