Subodh G., assistant professor of the Department Physics at Kerala University, and research scholar Vidhya Lalan have developed fifth-generation (5G) microwave absorbers that could serve as an effective shield against such radiation.

“The problems posed by EMI demanded immediate attention in this era of 5G technology and Internet of Things (IoT) when it has become difficult to undertake routine chores without the help of electronic devices and internet that work around electromagnetic waves. The need for EMI shielding materials, especially those suitable for high frequently applications, has never been as crucial as present,” Dr. Subodh says.
