Prof. Leo Felsen Legacy in Electromagnetics

Professor Leopold B. Felsen had been certainly one of the brightest minds among those who set the foundations of modern Electromagnetism. The breadth and depth of his scientific work on wave phenomena spanning over 50 years from the middle fifties until his death, in 2005 provided impactful contributions in acoustics, electrodynamics, seismology, and mathematical physics. His work elevated concepts in Electromagnetism, introducing ray- wave hybrids, complex source-point descriptions for intricate media, and leaky-wave and hybridized ray-mode descriptions for guided-wave phenomena. A catalyst for systematic knowledge development, Professor Felsen collaborated widely and mentored students globally, playing a pivotal role in shaping wave physics and engineering evolution.
