It is with much sadness that we write to express our final goodbye to a strong contributor and very active member of our Antennas and Propagation Society, Dr. Dimitris Psychoudakis. Dimitris was born in Thessaloniki, Greece on April 2, 1973. Dimitris excelled in Physics (BS) and Electrical Engineering (MS), and in 1999 moved to Ann Arbor, MI to pursue his PhD at The University of Michigan, completing his PhD degree in 2004. In 2005 he joined The Ohio State University ElectroScience Lab (dates) as a Post-Doctoral Researcher and later as a Senior Research Associate, where he stayed until 2012. Between 2012-2017 he worked at Samsung Research America as a Staff and Senior Staff Engineer. Dimitris joined the start-up Phazr (acquired by JMA wireless) in 2017 as the Director of EM-Antennas.

Dimitris was one of the first to pursue topology optimization methods to design textured ceramic dielectric antennas [1]. He later used these methods to pursue antenna size minimization using volumetric material optimization [2], [3]. He also played a key role at Ohio State in starting the research on wearable and embroidered antennas, including MIMO and diversity applications for antenna arrays. While at Samsung and later at Pharz he focused on 5G communications. Notably, his team at Samsung was the first to design and test 5G antennas for cellular and Base Station systems. The same team went on to demonstrate the world's first 5G telecommunication system.

Dimitris joined Phazr (2017), a Dallas start-up, where he served as Director and Principal Antenna Engineer. During his years at Phazr (later JMA Wireless), he continued to support 5G Research and Development.

Dimitris was a superb scientist, and equally skilled in simulations and measurements. He was mentor to many graduate students and will be remembered as a team player, and an active participant of the IEEE Antennas and Propagation activities. He published over 50 articles, mostly in IEEE periodicals, with several being highly referenced by the antenna community.

Dimitris is survived by his wife Dina, daughter Sofia, his brother Vasilis and mother Sophia.
