🎉 Beyond Thrilled to Share Our Latest Research Presented at EuMIC 2024!🎉 I’m excited to share that my latest research paper, co-authored with my colleague Woojun Lee, titled "Wireless Beamforming for Electromagnetic Field Focusing in Brain Tissue," was recently presented at the 2024 54th European Microwave Week (EuMC)! This paper investigates the possibilities of wireless deep brain stimulation (DBS) using a hemispherical phased antenna array design. Our work presents novel optimization approaches for improving the precision and effectiveness of wireless stimulation by directing electromagnetic fields into specific brain regions. Through varying frequencies and configurations, we’ve gained valuable insights into the interaction between electromagnetic waves and human brain tissue. Our simulations demonstrate these optimization approaches' enhanced performance, allowing for accurate electric field focus without needing highly packed sample locations. This finding has significant implications for future DBS applications that are more effective and non-invasive. A special thanks to Professor Dr. Jeffrey Walling, whose advice and ideas were invaluable in making this project come alive! Through varying frequencies and configurations, we’ve gained valuable insights into the interaction between electromagnetic waves and human brain tissue. Looking forward to pushing boundaries further in this exciting field! #Electromagnetics #EuMC2024 #VirginiaTech #Brain #Antenna #DBS #BiomedicalEngineering #Innovation #BioElectroMagnetic #Array #Tissue #Research

Delighted to share my latest research publication! Our paper titled "Frequency-Domain Photoacoustic Signal Analysis for Temperature Sensing" has been published in the IEEE Sensors Journal! Huge thanks to my mentor, Jayaprakash Naidu sir, for his invaluable guidance and support throughout this research journey. Accurate temperature monitoring is critical for success in cancer treatments based on thermal ablation such as High-Intensity Focussed Ultrasound (HIFU), Photothermal Therapy (PTT), and Radiofrequency Ablation (RFA). Our research explores using the frequency spectrum of photoacoustic signals to sense tissue temperatures.

"Electric and magnetic fields are complex physical agents whose potential health effects are the subject of much research. Particularly controversial are the biophysical mechanisms by which these RF fields may affect biological systems. General health effects reviews explore possible carcinogenic, reproductive and neurological effects. Health effects by exposure source are noted in radar traffic devices, wireless communications with cellular phones, radio transmission, and magnetic resonance imaging (MRI)." https://lnkd.in/ersG4i-K
