With more than fifty years of theoretical and technological innovations, Tatsuo Itoh was among the most famous and respected experts in electromagnetics and microwave techniques. He extended electromagnetic simulation to high-frequency applications, developing models that allow inclusion of relevant interactions between microwave circuit elements, their packaging, and the electromagnetic environment. His comprehensive field-based approach to global modeling helped establish the system-in-package concept important to smart phones. Itoh’s spectral domain method for microwave circuit analysis has become one of the most popular techniques for computer-aided design of microwave components. Late-career achievements included realizing metamaterials enabling leaky-wave antennas that can continuously scan from the backward wave region to the forward wave region as a function of frequency.

An IEEE Life Fellow at the time of his death, Itoh was a Distinguished Professor and the Northrop Grumman Chair in Electrical Engineering at University of California, Los Angeles, CA, USA.
