Title of Presentation:

Teaching Electromagnetic Principles through Simulation and Numerical Methods

Abstract:

Electromagnetics can be a challenging subject to teach for undergraduate students due to its reliance on abstract concepts, vector algebra, and advanced calculus. Traditional teaching methods often struggle to convey the physical intuition behind these mathematical formulations, resulting in a disconnect between theory and real-world applications.

This lecture explores how the integration of numerical methods and interactive simulation tools can significantly enhance the teaching and learning of electromagnetic principles. Using the TaraNG simulation platform, students can visualize field distributions, wave propagation, and boundary interactions in an engaging and intuitive manner. TaraNG’s real-time animations and user-friendly interface make complex electromagnetic behavior more accessible. Furthermore, the platform provides direct access to source code for mathematical modeling, allowing students to explore the underlying numerical methods and deepen their understanding of the mathematics driving the simulations. This approach not only improves conceptual clarity and retention but also fosters curiosity and enthusiasm for computational electromagnetics.

Short Bio:

Swapnil Gaul is the Founder and Director of NUMEREGION TECHNOLOGY. He completed his Master’s degree from IIT Kharagpur (2011–2013) with a specialization in RF and Microwave Engineering, where he worked on computational electromagnetics and numerical techniques under the guidance of Prof. Ramesh Garg. After completing his studies, he joined NI Logic, working with simulation software and EDA tools such as Altair’s FEKO, ESI’s CEM Solution, and QuickField. During this time, he demonstrated these tools at over 75 engineering institutes across India and consulted for leading research organizations like ISRO and DRDO. He has published two research papers: one on “RCS Prediction with MOM, MLFMM, PO & PTD Methods” in collaboration with Defense Laboratory Jodhpur, and another on “EMC Analysis of Cable Harness using TLM Method,” presented at Indian Antenna Week 2017 in association with ESI Group. He also contributed to the development of a PSO Optimization Toolbox for MATLAB. While engaging with students during his demonstrations, he realized that many struggled with using complex simulation tools and saw the need for a unified solution focused not on software proficiency, but on deep conceptual understanding through simulations. Motivated by this insight and backed by substantial industrial experience, he left his job to develop hands-on simulation packages aimed at concept-driven learning. Building upon his master’s project, he transformed it into a commercial product and founded NUMEREGION TECHNOLOGY to pursue this vision strategically and make practical engineering education more accessible.
