A Parabolic Metamaterial Lens for Matching Between Parallel-Plate Waveguides In Memory of W. Ross Stone

This author of this work had a professional relationship with Ross Stone which lasted for decades and evolved into friendship between Ross and his wife Sue, and the author and his wife Shelly. The professional relationship involved service to both the IEEE and the URSI communities, but on two occasions it dealt with scientific matters. In 1989, Ross invited the author and two colleagues to contribute a paper to a book which he edited (Radar Cross Sections of Complex Objects, ed. W.R. Stone. New York: IEEE Press, 1989). Thirty years later, Ross and the author collaborated in writing the USNC chapter in a book celebrating the first centennial of URSI (W.R. Stone and P.L.E. Uslenghi, “One Hundred Years of Radio Science in the United States of America (1919-2019)”, pp. 362–390 in: 100 Years of the International Union of Radio Science, eds. P. Wilkinson, P.S. Cannon and W.R. Stone. Gent, Belgium: URSI Press, 2021). The present work contains a novel solution to a boundary-value problem and it is dedicated to Ross' memory.
