Remembering Per-Simon Kildal: Soft in heart and hard in technical work

摘要

Professor Per-Simon Kildal passed away on April 21, 2016, after a very short period of illness. He was born on July 4, 1951. He chaired the Division of Antenna Systems of the Department of Signals and Systems at Chalmers University of Technology. He authored an antenna textbook and many journal articles and conference papers. He designed two very large antennas, including the Gregorian dual-reflector feed of the Arecibo radio telescope. He was the originator of the concept of soft and hard surfaces, recently resulting in the gap waveguide, a new low-loss meta-material-based transmission line. His research group pioneered the reverberation chamber into an accurate measurement tool for antennas and wireless terminals. Prof. Kildal was the recipient of two Best Paper Awards for articles published in the IEEE Antennas and Propagation Transactions, and he was the recipient of the 2011 Distinguished Achievements Award of the IEEE Antennas and Propagation Society.
