Summary:

Successfully invented the first of it’s kind surface waves based near-field Wireless communication system for Hyundai Heavy Industries and Samsung Heavy Industries, which can communicate through ship walls and hull. This provides the shipping industry with a freedom to go wireless. The invention was a result of precise guidance of Prof. Dr. Franklin Bien, BICDL Ulsan National Institute of Science and Technology.

The RF signals are shielded down due to EMI shielding offered by the complex maze of metal structures. Hence several kilometers of cables are setup in a typical ship or Semi-Submersible Oil Rig. But with the surface wave near-field wireless communication system all these problems have been addressed. The same technology has been developed to setup wireless safety alarms, wireless power transfer and wireless digital data transfer. Currently, working towards IEEE industry standards for the invention. Also invented a wireless power transfer based touch, proximity and hover sensor. The resulting publications received honors from IET and IEEE sensors council. Both the inventions were done during the PhD candidature which were partially funded by- Hyundai Heavy Industries, Samsung Heavy Industries and National research foundation of Korea(South).
