About

Postdoctoral Researcher on the topic related to detection of Spinwaves in magnetic insulator YIG using Lockin Thermography technique. During PhD, I have worked on Microwave absorption (2-18 GHz frequency range ) and Electromagnetic interference (EMI) shielding behaviors of composites based on conducting polymer (Polyaniline), hard ferrimagnetic hexaferrites, soft magnetic Yttrium Iron Garnet (YIG), metallic iron particles, metal (Fe/Co/Ni) doped carbonaceous materials along with microwave transparent paraffin wax or PVDF. Also, I have been collaboratively worked on the topics of Magneto-rheological fluid, Non-linear optics, Corrosion protect of metals, Mössbauer spectroscopy, Gamma ray induced phase transformation in ferrites, Solid state Zero field NMR studies of 57Fe and 59Co nucleus, Photocatalysis and defects studies in ZnO based materials and dielectric properties of ceramics.
