IMPRINT: Electronically tuned ultra-wide band Microwave Monolithic Devices using Magnetic Nanostructures

IIT Delhi researchers are working on a project that will design and develop light weight, cost effective wafer-thin microwave devices (10 to 40 GHz) range for the next generation communication and military applications.

The project is a part of IMPRINT programme, an MHRD supported Pan-IIT + IISc joint initiative to address the major science and engineering challenges of the country. It will be the first of its kind to promote the Make In India programme of Government of India, which can be produced in India without any foreign collaboration.

The researchers will collaborate with scientists from JNU-Delhi and Rohde & Schwarz India Pvt Ltd, Delhi to design, fabricate and characterize frequency tunable, compatible with Monolithic Microwave Integrated Circuit(MMIC) technology, small light-weight, cost-effective, high-frequency (>10GHz).

Dr P K Muduli, Principal Investigator said: “We will develop electronically tuned microwave monolithic devices such as filter, phase shifter, and isolator using innovating techniques that involve nanostructured magnetic elements, magnetic nanowires, and ultra-small waveguides.”

The nanowires and films will be incorporated into ultra-small microstrip waveguides to produce reciprocal/nonreciprocal devices operating above 10 GHz. A reciprocal device is one in which the power losses are the same between any two ports regardless of direction of propagation of the microwave signal. Magnetic/multiferroic nanowires will be developed with bottom-up and top-down approach and will be incorporated into microstrip waveguides to produce the reciprocal and nonreciprocal response.
