Professional Experience

Research Assistant, Microfabrication Group Jan 2016- Till Date (2 + years) Center for Advanced Microstructure and Devices (CAMD) Area of Focus: UV lithography, X-ray Lithography, X-ray Mask Fabrication, Microfabrication and LIGA techniques, Electroplating, Diffraction Gratings, and 3-D printing. Projects:

Fabrication of High Aspect Ratio Gratings

Summary: The high aspect-ratio gratings were fabricated for Talbot interferometer using LIGA techniques. The structures aspect-ratio, 15 were achieved by exposing PMMA negative resist to X-rays at XLRM beamline in LSU CAMD. The experiment requires LIGA techniques such as resist coating, photo-exposure, Wet etching of CuOx and TiOx, Electroplating, surface planarization using Flycutting, polishing and PMMA bonding. With iterations, optimum developing parameters and exposure dose were finalized. The adhesion was improved through various surface modification techniques, which is essential for high aspect-ratio structures. Fabrication of X-ray Mask with Silicon Nitride Windows Summary: An X-ray mask with silicon window was fabricated using NR 26 negative resist and UV lithography. The fabrication requires LIGA techniques such as resist coating, photo-exposure, Wet etching, Electroplating, and backside etching of Silicon wafer. E-Beam Writing

Summary: 50nm structures with an aspect ratio of 6, were fabricated on a gold coated glass substrate. The photo resist used is PMMA-950k 6% & 9%. E-beam writing is done using SEM, NPGS software. Hot embossing for microfluidic devices

Summary: Molds with different micro structured fluidic channels were replicated several times on a PMMA sheet with high aspect ratio, each mold and replicated sheets were observed under microscope.

Projects:

Wireless Power Transfer through Microwaves

Summary: Microwave based Wireless power transfer (WPT) is a mid-range power transfer mode. In WPT the electrical power is converted to RF signals. These RF signals are then transmitted through a transmitting antenna. Later, these RF signals have received at a receiving antenna. Further, the received RF signals are converted back to electrical power with the help of rectifiers. By applying the beam-steering fundamentals the power can be transmitted to the moving targets or sensors such as electric vehicles. Resonance based Wireless Power Transfer System

Summary: Resonance based Wireless power system is a short range WPT mode. If two coils are resonating at an identical frequency, then the power is transferred from one coil to another coil. For the maximum power to be transferred impedance matching between both Tx and Rx coils is needed. The efficiency of a system is marked by mutual coupling between coils and Q-factor of a coil. To remove the nonlinearity and to increase the efficiency of the system coupled mode theory is used which removes the nonlinearity from the system. Education – Internship
