Research Topic: Coupling of stochastic field into cables with non linear loads, tests in medical equipment
Background:
I hold a Bachelor of Technology in Electronics and Communications from the Open University of Sri Lanka (OUSL) and a Master’s degree in Electronics, including a professional internship, from Queen’s University Belfast. From 2019 to 2022, I worked as a lecturer, leveraging my academic expertise to teach and mentor students. In addition, I contribute as an external author, writing course materials for OUSL.
How did you become a part of NEPIT?
The interest towards electromagnetism drives me towards the PhD. So I have applied to the NEPIT position, where I got to know through online vacancy advertisement
What is NEPIT according to you?
Solutions for problems related to EMI using reveberation chambers. Applications can help towards human wellbeing on many aspects
Role in NEPIT?
PhD research focuses on investigating how random electromagnetic fields couple to cables with nonlinear terminations, with the ultimate goal of minimizing interference in MRI environments caused by other medical devices. By conducting experiments in reverberation chambers, it will analyze the stochastic coupling effects on cables terminated with nonlinear components and identify the resulting distortions and interference patterns. This approach will helps to develop practical solutions to reduce unwanted electromagnetic interactions, thereby enhancing the reliability and safety of MRI imaging when multiple medical devices operate within the MRI room.
Plans for immediate and distant future?
Conducting simulation based and reveberation chamber based experiments on coupling effect of stochastic field into single wire and double wire transmission lines with non linear terminations. Conduct emmision and immunity tests for medical devices inside reveberation chamber and investigate a solution to recuse interference effects towards MRI imaging.
