Having set up a Radio Frequency (RF) laboratory, the Centre has received funds from DST-SERB to make a 4-element radio interferometer at 1.4 and 5 GHz. Other than constructing this pathfinder, the RF lab also helps characterize RF properties of novel materials (made by one of the Associate members, Dr. Somaditya Sen ). Four dishes, of 2.5 metre diameter, are being readied for the interferometer. Currently, 1 PhD student and 1 JRF are working in this area.
