Abstract: As the operation frequency increases for 5G/mmWave communication, new challenging issues becomes raised. As an RF engineer, I can see new challenges with 5G/mmWave applications. One of new challenges is the unwanted reflection from dielectric objects which start causing significant issues on the signal transmission because the thickness of dielectric objects and materials is getting close to the wavelength of the signal. The wavelength is about 10mm in air at 28GHz and the wavelength is about 3mm in air at 110GHz. We will discuss these challenging problems and the solutions.
Biography: Dr. Kim received his B.S. and M.S. degrees in Electronics Engineering from Korea University, South Korea, in 2001 and a Ph.D. degree in Electrical Engineering from the University of Minnesota, Minneapolis, MN, in 2008. Since 2008, his research area includes electromagnetics and metamaterials at 3M Corp. Research Lab in St. Paul, MN; current project is working on 5G/mmWave material developments. His publication at 3M includes 139 IS submissions and 45 patents filed.
