We work on fundamental and applied aspects of Computational Electromagnetics (CEM), scientific machine learning, uncertainty quantification and optimization techniques, to enable advances in current, emerging and future wireless communication components (antennas, reconfigurable intelligent surfaces) and systems (5/6 G and beyond).

Generalizable Neural Network Models for Wireless Propagation Modeling
Generalizable Neural Network Models for Wireless Propagation Modeling
We have introduced neural network based propagation models that can generalize with respect to geometry, position of transmitter and receiver and operating frequency of indoor/outdoor channels (i.e. they can rapidly solve new geometries, with transmitters operating from new positions and new frequencies, well beyond those included in the training set).
Multiphysics Modeling with Physics-Informed Neural Networks
Multiphysics Modeling with Physics-Informed Neural Networks
We demonstrated a new paradigm for solving multiphysics problems utilizing robust, single-physics techniques (such as FDTD or finite elements) combined with neural networks to model associated physics (such as thermal effects).
Propagation modeling with ray-tracing and the vector parabolic equation method (VPE)
Propagation modeling with ray-tracing and the vector parabolic equation method (VPE)
Accurate modeling of radiowave propagation at 2.4 GHz along 3 km of tunnels and open-air sections in the London (UK) underground (measurements provided by Thales Canada/UK). Details for this work are provided in: N. Sood et al, "Integrating Physics-Based Wireless Propagation Models and Network Protocol Design for Train Communication Systems," in IEEE Transactions on Antennas and Propagation, Dec. 2018.
