My research focuses on addressing these challenges and ultimately realizing energy efficient passives for 5G and beyond. Firstly, using CMOS/packing compatible fabrication methods and design techniques, I experimentally demonstrated various mm wave devices such as filters, antennas, and low temperature processed magnetic material based nonreciprocal devices. Using electromagnetic simulation tools such as High Frequency Structural Simulator (HFSS ANSYS) and Advanced Designed System (ADS Keysight Technologies) impact of various loss factors on device performance is analyzed. Further, to minimize these losses in devices especially due to copper conductor, I also studied and experimentally verified new low loss conductors in Ka and V band using multiple nanolayers of non-ferromagnetic and ferromagnetic materials. Moving forward, I aim to implement tunable low loss nonreciprocal devices by integrating them with ferroelectric materials such as Barium Strontium Titanate (BST) targeting mm wave frequencies.

Over the past 50 years technology underwent drastic makeover, making Internet of Things (IoT) ubiquitous. It is estimated that by 2025 we will have nearly 38.6 billion IoT devices. To accommodate this huge device traffic, achieve higher data rates and low latency upcoming 5G is trying to broaden the spectrum range by transitioning to mm wave frequencies (i.e. 24-38 GHz and above 60 GHz) along with the sub 6 GHz range. But the major challenge is that, as the frequency of operation increases, losses due to substrate dielectric, roughness and conductor degrades the performance, causing high power consumption in mm wave devices and high-speed interconnects.
