This is a postdoctoral position in Prof. Michal Mrozowski’s research project: “New concepts in microwave filters, phasers and multifunctional passive circuits for future RF systems”. The goal of this project is to develop new concepts for several classes of RF/microwave passive devices with novel functionalities and to propose the underlaying theory for their efficient design with the properties that are desired for their use in novel radio systems. These RF/microwave passive devices are of interest in emerging RF chains to be used in novel communications and radar systems, and Internet of Thing (IoT) sensors for human-centered wireless scenarios. The project will put special emphasis on the engineering of new types of bandpass filters, phasers, as well as multi-functional and reconfigurable passive components with enhanced performance and frequency-agile characteristics. The post-doc on this position will contribute to the synthesis of filters and phasers with dispersive couplings and also to multi-functional and reconfigurable passive components with co-designed RF capabilities. The postdoctoral appointment is for 30 months.
