Title: Optimal Currents and Shape Synthesis in Electromagnetism
Abstract: Dealing with all antenna characteristics solely by means of currents flowing on the antenna body opens new possibilities of how to reformulate old, yet unsolved, problems in classical electromagnetics, particularly in the theory and design of electrically small radiators. A key part of the talk is, therefore, an introduction of the so-called source concept which involves diverse methods of calculation, decomposition, and the modification of electric and magnetic currents, i.e., the sources. It will be demonstrated how – thanks to knowledge gained in the last ten years – we are slowly, but surely, approaching a point at which a complete antenna synthesis will be possible. One of the exciting novelties within the source concept, topology sensitivity for the method of moments, will be discussed in detail, including its implementation and examples. A precise and efficient numerical implementation of source concept is an inevitable part of its practically-oriented development. With respect to this, the MATLAB toolbox AToM, currently being developed at CTU in Prague, will be presented. The talk will conclude with other perspectives of the topic and questions to be addressed in the near future.
