The current need for wireless systems operating effectively in the near-field region of the radiating device highlights a significant shift, both in industry and research. Nearfield (NF) conditions, where standard far-field approximations might fail to provide accurate results, demand a specialized approach to the development of radiating devices and propagation models. These are essential for developing the next generation antennas to meet the stringent requirements of near-field environments in many applications. This course will focus on the fundamentals of NF radiating systems and as well as techniques for analysing, design, and modelling antennas for NF systems for communications and sensing.
