Salazar-Cerreño received a B.S. In ECE from the University A ntenor Orrego\, Trujillo\, Peru\, and an M.S. degree in ECE from the Unive rsity of Puerto Rico\, Mayaguez (UPRM). In 2011\, he received his Ph.D. de gree in ECE from the University of Massachusetts\, Amherst. His Ph.D. res earch focused on development of low-cost dual-polarized active phased arra y antennas (APAA) for the Engineering Research Center for Collaborative Ad aptive Sensing of the Atmosphere (CASA). After graduation\, Dr. Salazar-Ce rreño was awarded a prestigious National Center for Atmospheric Research (NCAR) Advanced Study Program (ASP) postdoctoral fellowship. At NCAR\, he worked at the Earth Observing Laboratory (EOL) division developing airbor ne technology for two-dimensional\, electronically scanned\, dual-pol phas ed array radars for atmospheric research. This is a critical tool for stud ying weather and related hazards\, especially for retrieving dynamic and m icrophysical characteristics of clouds and precipitation over rugged terra in or the open ocean\, where other radar systems can have major limitation s. In July 2014\, he joined the Advanced Radar Research Center (ARRC) at T he University of Oklahoma as a research scientist\, and became an associat e professor at the School of Electrical and Computer Engineering in August 2021. His research interests include high-performance\, broadband antenn as for dual-polarized phased array radar applications\; array antenna arch itecture for reconfigurable radar systems\; APAA\; Tx/Rx modules\; radome EM modeling\; and RF and hardware development for characterizing and calib rating APAA and millimeter-wave antennas. In 2019\, Dr. Salazar was awarde d a William H. Barkow Presidential Professorship. Presidential Professors inspire their students\, mentor their undergraduate and graduate students in the process of research and creative scholarly activity within their di scipline\, and exemplify to their students and their colleagues the ideals of a scholar through their endeavors in teaching\; research and creative scholarly activity\; and professional and university service and public ou treach.

The fast evolution of RF technology enables the development of new creative phased arrays architectures that offer unprecedented performance for communication\, remote sensing\, and weather observation. Fast volumet ric scanning updates (<\; 20 secs)\, and wide-scanning (90 to 170 deg.) with ultra-low cross-polarization isolation (<\; 40 dB) are some of the main features of new phased array architectures. An overview of current an d new trends in phased-array architectures and technology for multifunctio n\, reconfigurable\, shared-apertures\, multiband\, and ultra-wideband arr ays and \;radar systems\, focusing on scanning performance including < span class=SpellE>mmWave technology will be presented.
