Abstract
There is currently a great interest within both academic and industrial research in finding new ways for exploiting the rich, hitherto unexplored, spatial structure of electromagnetic radiation in the near zone. This interest is motivated by two factors. First, the monotone increase in the density and complexity of working EM environments, causing devices to become either immersed in nearby near field radiation or forced to interact with each other in the near zone. Characterizing and designing devices or basic material structures working in such non-standard conditions is a challenging topic that has not been not well explored in the specialized literature so far. The second factor is the possibility to develop a new generation of applications depending fundamentally on the near field, achieving EM functions not seen before within the traditional perspective of the far-zone regime. The short course will therefore attempt to provide new comprehensive view on this topic based on recent findings by the authors directly addressing the problems above.
Course outline
The short course will provide a brief survey of the progress made in theory in each of these topics, which includes comparison with previous knowledge and the essential advances made in this area during the last few years. It will be indicated how the development can be put in use to introduce new measures for numerical modelling, for example how to compute energy localization and how to synthesize a given near field, how to attack the problem of NF matching, how to filter and shape radiation in the NF zone.
The short course will also address EM engineers and researchers who are looking for methods and techniques capable of dealing with the increasingly important problem of measuring system performances in complicated and changing near-field environments. We will provide suggestions about how new measurement methods can be developed based on our research during the last five years, which has been concerned with fundamentals and foundations of the relevant theoretical, experimental, and computational methods.
The structure of the course is the following:
- General Introduction and historical motivation: Why NF engineering now?
- An Introduction to Near Field Theory (New Foundations, which include Spatial and Spectral Theories.)
- A New Look at EM Energy (reactive, localized, and stored energies).
- Analysis of Near-Field Interactions Using the Antenna Current Green’s Function Method: Theory, physics, implementation, and examples.
- NF Engineering and Electromagnetic Mutual Coupling: Theory and methods
- The Design and Development of NF Devices: Basic Principles and Examples:
- Design of NF synthesis arrays.
- The physics and requirements of NF matching.
- Nonlocal Metamaterials (MTMs) and NF Engineering of Energy in the Near Zone:
- Theory and Prospects of Realization of new MTMs.
- Applications for energy control and transfer.
- Comparison between conventional MTM and the new generation of nonlocal MTMs.
- Near Field Engineering and Nanotechnology: Overview on nano-electromagnetics in light of Near-Field Engineering.
The short course will address engineers, scientists, industry representatives who are looking for methods and techniques capable of dealing with the increasingly important problem of measuring the performance of systems embedded into complicated and changing near-field environments. We will provide hints about how the new measurement methods can be developed based on our research, which has been concerned with fundamentals and foundations of the relevant theoretical, experimental, and computational methods. Moreover, the survey of the theoretical part will stimulate the interest of researchers looking for solutions to outstanding problems such as stored energy, mutual coupling compensation, and synthesis algorithms.
