Recent Courses

Advanced EM I & II (taught at TCIS-TIFRH)

This course is offered to the Ph.D. students of TCIS as their course work. It covers advanced topics fron electrodynamics and some of the recent advances in nanooptics and photonics. These include perfect lensing with negative index materials, extraordinary transmission, superresolution, Bloch oscillations, Talbot effect etc.
Essential: Mathematical Methods I (MM I)
Prerequisites: Basic Linear Algebra, Analytical Geometry, Trigonometry, Mathematical Analysis.
Wish list: Working knowledge of Matlab and Mathematica
Note: Some assignments will require basic matlab and mathematica coding for visual perception of functions, derivatives, integrals, conformal mapping, and also for integral transforms and for solving ODE’s and PDE’s.

Oscillations Waves and Optics

This is an introductory course on waves and oscillations familiarising the students with wave optics. The course is aimed at second year undergraduates. For a list of contents click here. Send me a request for the lecture notes here.

Laser Physics

This course is for the IIIrd semester M.Sc. students and includes full density matrix approach for light-matter interaction. The course is designed following the books by Sargent Scully and Lamb, Siegman. Recently it was revamped completely making use of the excellent lecture notes of my close friends Prof Fabien Bretenaker on laser Physics and Prof Fam Le Kien on Density Matrix Theory.

Nonlinear Optics

This Course is targeted at the final IV-th semester M.Sc. students specializing in Optics. Starting from the Response Function theory, the course introduces linear and nonlinear susceptibilities with ample coverage of the symmetry properties. Both classical and semiclassical methods are applied to derive the expressions for the susceptibilities. Rest of the course deals with macroscopic phenomena and covers numerical simulation of harmonic generation, optical bistability, solitons, four-wave mixing and phase conjugation etc.

EM Theory I and II

These are fairly standard University level courses for M.Sc. Ist and II-nd semesters. For assignments given in this course click here. Recently a series of 38 video lectures were delivered for the RGUKT undergraduates. In order to have access to these video lectures you may visit the RGUKT Course Site.

Microwave Laboratory

This Laboratory experiments are aimed at illustrating some of the crucial devices and concepts at microwave frequencies including klystrons, waveguides, impedance matching and Smith Charts (its relation to conformal mapping in Complex Analysis), T-bends, resonators, antennas and feeders etc. For lab manuals prepared by me, mention the experiment and send me a request.

Nanooptics and Plasmonics

This course aims at giving a flavour of recent trends in nanooptics and plasmonics. The topics include surface and localized plasmons, negative and hyperbolic materials, spin-orbit interaction in nano structures and in structured light, extrao rdinary transmission, superresolution etc. Click here for syllabus:plasmonics

Process , Device and Circuit Modeling and Analysis (PDCMA)

This course is offered to the M.Tech. Electronics students elaborating on the fundamentals of process simulation, device modeling and circuit simulation. It is computation intensive and requires the understanding of basic underlying physical concepts from diverse areas. A good knowledge of numerical techniques is also an essential ingredient
