Abstract

In this talk, we will present two novel cost-effective metasurface designs which can achieve broadband polarization conversion. The designs are optimized in CST Microwave Studio Suite to obtain the set of parameters that gives the highest polarization conversion ratio (PCR) for the largest frequency range. We fabricated two prototypes. The first prototype achieved a PCR>0.9 between 8.9 and 12.2 GHz. The second prototype achieved a PCR>0.9 between 8 and 17.85 GHz.

Presenter Bio

Tse-Tong CHIA received a B. Eng. Degree (first-class honors) from the National University of Singapore in 1986 and his M.S. and Ph.D. degrees from Ohio State University in 1991 and 1994, respectively. He has been with the DSO National Laboratories, Singapore, since 1986, where he held various roles. He is currently a Distinguished Member of the Technical Staff. He is also an adjunct Senior Principal Research Scientist at the Temasek Laboratories at the National University of Singapore. His former interests were in computational electromagnetics and scattering.

Now he focuses mainly on electromagnetic design and applications, including lenses, reflectarray/transmit array antennas, and metasurface. He has more than 10 years of experience using CST Microwave Studio. He actively supervises students from as young as 15 years old to undergraduates in school projects and internships and introduces them to CST as the electromagnetics simulation software of choice.
