Optical and Microwave Metamaterials, Nano/micro-photonics and Fabrications, Antenna Engineering, RF and Microwave Devices
Dr. M. Qasim Mehmood has received his BS degree in Electronic Engineering from International Islamic University Islamabad (IIUI) in 2008. Same year he started his MS from Ghulam Ishaq Khan Institute (GIKI) and joined there as a Lecturer upon completion of his MS in 2010. He has completed his PhD from National University of Singapore under the supervision of well-known professors Dr. Cheng-wei Qiu, Dr. Aaron Danner and Dr. Teng Jinghua. Currently he is heading NanoTech lab at ITU, where innovative ideas and impactful research-outcome is the ultimate goal. His research is essentially in the area of optics and nano-photonics: more precisely it includes the demonstration of exotic phenomena (via ultra-thin nano-structured devices) e.g., on-chip orbital angular manipulation, beam-steering, spin-orbital coupling, three dimensional holography, polarization filtering and light absorption etc. All of his work incorporates vigorous theoretical modeling, numerical calculations and experimental investigations.
He has plentiful experience of nano-fabrications at different clean-rooms such as Institute of Material Research Engineering (IMRE) A*STAR Singapore, Spin Energy Lab (SEL) NUS Singapore and National Institute for Nano-materials Technology (NINT) POSTECH South Korea. He has active research collaborations with Harvard, NUS, POSTECH, SUTD and Wuhan University, where his students (MS and PhD) and research associates go for attachments to perform their fabrications.
