Research expertise: Analytic theory of natural and artificial media, measurement and design of the electromagnetic properties of materials, magneto-dielectric materials for broadband antennas and electromagnetic structures, optical scattering of sub-wavelength objects in complex environments and nanophotonics, time domain computational electromagnetics.

During his 20 years in the aerospace industry, Rodolfo Diaz has worked on many aspects of the interaction between electromagnetic waves and materials, from lightning protection on the space shuttle through the design of microwave lenses and high-temperature broadband radomes for radar missiles to the design and manufacture of radar-absorbing structures for Stealth applications. He joined ASU faculty in 1998 as an associate professor of electrical engineering. Diaz is the former associate director of the Consortium for Metrology of Semiconductor Nanodefects, former interim director of the Consortium for Engineered Materials in the School of Materials at ASU. He also holds 30 patents ranging from the design of broadband radomes to the amplification of magnetic fields. From 2010 to 2012 he was on a part time IPA assignment to the Sensors Directorate, Meta-Electronics Branch, RYDM, WPAFB in Dayton, Ohio.

Honors and distinctions: 1994 Association of Interamerican Businessmen Award to Distinguished Young Executives in the Professional Category for Excellence in Engineering, San Juan, Puerto Rico.
