Friday, December 2, Storer Hall 1322, 12:10pm-1:00pm

Speaker: M.C. Frank Chang
Electrical Engineering Department, UCLA

Host: Professor Anh-Vu Pham


The talk will present recent developments in synthesizing Digital Controlled Artificial Dielectric (DiCAD) by using lithographically defined 3-dimensional metal periodic structures under differential transmission lines in deep-scaled CMOS to achieve wide permittivity tuning range (>20) in real-time via CMOS switching controls and showcase demonstrated mm-Wave and Sub-mm-Wave communication/imaging circuits/systems based on such dielectrics. The talk will also discuss possible synthesis of Digital Controlled Artificial Magnetic (DiCAM) materials with tunable permeability in dilute magnetic semiconductors for broad/multi-band reconfigurable radio applications.


Dr. Frank Chang is currently the Wintek Chair Professor and the Chairman of Electrical Engineering Department, UCLA. Before joining UCLA in 1997, he was the Assistant Director and Department Manager of the High Speed Electronics Laboratory at the Rockwell Science Center, Thousand Oaks, California (1983-1997). Throughout his career, his research has primarily focused on the development of high-speed semiconductor devices and integrated circuits for RF and mixed-signal communication, Radar, and imaging systems. He was elected to the National Academy of Engineering in 2008 for his development and commercialization of GaAs power amplifiers and high-speed mixed-signal integrated circuits. He is an IEEE Fellow and received IEEE David Sarnoff Award in 2006 for developing and commercializing HBT power amplifiers for modern wireless communication systems (especially the cell phones).
