Nacer E. Chahat is a French-American engineer and researcher at the National Aeronautics and Space Administration (NASA) Jet Propulsion Laboratory.

Early life and education

Chahat was born in Angers, France to a family of Algerian descent.[1] He was educated at Palissy High School.[2] He obtained his master's degrees in electrical engineering from École supérieure d'ingénieurs de Rennes|Ecole Supérieure d'Ingénieurs de Rennes (ESIR) and in telecommunication from the Institute of Electronics and Telecommunications of Rennes (IETR), University of Rennes 1 in 2009.[3][2] He completed his Ph.D. in signal processing and telecommunications at the IETR, University of Rennes 1, in 2012.[3][4]

Career

Chahat has been associated with the National Aeronautics and Space Administration (NASA) Jet Propulsion Laboratory (JPL), since 2013.[3][1] Initially, he joined as a Microwave/Antenna Engineer and later took on the roles of Technical Section Staff and Product Delivery Manager in 2017.[5] He became SWOT Payload System engineer in 2019.[6]

At NASA's Jet Propulsion Laboratory (JPL), Chahat has contributed to several projects, including the Mars Helicopter, Mars 2020, SWOT, Europa Clipper, Mars Cube One, RaInCube, and others.[6]

On April 19, 2021, Chahat was part of the Jet Propulsion Laboratory team that successfully made Ingenuity, the first powered-controlled aircraft to fly on another planet.[7]

In 2022, Chahat was named an IEEE Fellow, recognized for his contributions to spacecraft antennas and propagation, and became one of the youngest fellows of IEEE.[3]

Research

Chahat specializes in antenna design and electromagnetic interference and compatibility (EMI/EMC) analysis for space missions.[8] He also works across a wide range of frequencies, from UHF to THz, applied in communications, RADAR, imaging systems, satellite communications antennas, wearable and flexible antennas, and antennas for remote sensing and radio astronomy.[8]

Chahat's notable contributions to NASA missions include the design of the Raincube Ka-band deployable mesh reflector, the Mars Cube One X-band antennas, the Europa lander antenna, and communication tools for the Mars Helicopter mission.[8][9]
