Rodolfo Diaz

Diaz_RodolfoWEBAssociate Professor
ASU Directory Profile

ISTB4 472

Research expertise
Optical scattering of sub-wavelength objects in complex environments and nanophotonics, analytic theory of natural and artificial media, measurement of electromagnetic properties of materials, combined computational mechanics and electromagnetics

During his 20 years in the aerospace industry, Professor 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 the ASU faculty in 1998 and currently is an associate professor of electrical engineering. Professor Diaz is the former associate director of the Consortium for Metrology of Semiconductor Nanodefects, interim director of the Consortium for Engineered Materials in the School of Materials at ASU. He also holds 21 patents ranging from the design of broadband radomes to the amplification of magnetic fields.
