Specialization: VLSI, ( Thesis final submission stage- Completing by November 2015)

Thesis title: GPU  accelerated  MoM  based  radiation  analysis using NVIDIA  CUDA

(Advisor:  Prof.  Pradeep Chhawcharia, Director  Research, Techno NJR)

Development   languages : C, CUDA C, MATLAB ;  Simulator : FEKO

Synopsis: In this thesis, GPU is used to accelerate most compute intensive phase of CEM method MoM. Scattering and radiation analysis of metallic body using RWG basis and weighting function is considered for serial and parallel implementation. The peak speedup was measured to be about 30 that turn up about 4× faster execution when considering total MoM solution process.
