National Taiwan University (NTU) Honors Distinguished Alumni, Professors Frank Chang and Kuo-Nan Liou
Professors Frank Chang and Kuo-Nan Liou were honored by NTU with the Distinguished Alumnus Award during its 85th anniversary ceremony at the NTU Sports Center on November 15, 2013. The award celebrates alumni who have attained international recognition and contributed to the advancement of their chosen fields or industries.
Professor Frank Chang is chair and a distinguished professor in the Electrical Engineering Department and elected Member of the National Academy of Engineering and the Academia Sinica. Professor Chang is known for his leading researches in mm/sub-mm-wave (or Terahertz) CMOS integrated circuits for communication, interconnect and imaging systems. He invented and synthesized Digitally Controlled Artificial Dielectric (DiCAD) by using CMOS periodic metal structures to vary its permittivity in real-time (up to x20) for realizing reconfigurable multiband/mode radios. He developed a new class of Multi-Gbps Radio-on-a-chip at the 57-65GHz ISM band with unprecedented self-diagnosis/healing capabilities to boost/recover its system performance from temperature/process variations and from aging effects. He invented multi-band (N-band) RF-interconnect, beyond the traditional baseband-only interconnect, to enable inter-core communications in Chip-MultiProcessor (CMP) and inter-chip communications between CPU/Memories with N-times bandwidth, real-time re-configurability and unique multicast capabilities.
Professor Kuo-Nan Liou is a distinguished professor in the Atmospheric and Oceanic Sciences Department with a joint appointment in Electrical Engineering, and Director of the UCLA Joint Institute for Regional Earth System Science and Engineering. He is also a member of National Academy of Engineering and a member of Taiwan’s Academia Sinica. He is the recipient of the 2013 American Geophysical Union’s Roger Revelle Medal. Professor Liou has been the foremost pioneer in light scattering by ice crystals; his unified theory, encompassing all sizes and shapes, has transformed the field of cloud remote sensing. He discovered the backscattering depolarization principle to distinguish between ice crystals and water droplets, developed the theory and numerical scheme to retrieve atmospheric heating rates, and innovated a cloud-precipitation-climate model to investigate links between cloud particle sizes perturbed by greenhouse warming and air pollution, universally referred to as the second indirect effect in aerosol-cloud feedback.
