 Research of my work

My current research is at the antenna, microwave circuit, and electromagnetic engineering. A primary research thrust is the antenna design. I use theory, simulations, prototyping to validate research ideas. I am also interested in applied engineering mathematics to electromagnetic problems. Recently, I am developing wireless power transfer, MIMO antenna, RFID antenna, and visible light communication.

 

Research Topic of Interest: MIMO antenna, RFID antenna, IoT, LoRaWAN, millimeter wave, 5G Communication, precision agriculture, Phytomonitoring system, antenna for GPR
