Course Objectives:

  • Students will demonstrate skills in scientific inquiry, problem solving and laboratory techniques.
  • Students will be able to demonstrate competency and understanding of the concepts found in Quantum Mechanics, Fiber optics and lasers, Semiconductor physics and Electromagnetic theory and a broad base of knowledge in physics.
  • The graduates will be able to solve non-traditional problems that potentially draw on knowledge in multiple areas of physics.
  • To study applications in engineering like memory devices, transformer core and electromagnetic machinery.

Course Outcomes: Upon graduation:

  • The student would be able to learn the fundamental concepts on Quantum behaviour of matter in its micro state.
  • The knowledge of fundamentals of Semiconductor physics, Optoelectronics, Lasers and fibre optics enable the students to apply to various systems like communications, solar cell, photocells and so on.
  • Design, characterization and study of properties of material help the students to prepare new materials for various engineering applications.
  • The course also helps the students to be exposed to the phenomena of electromagnetism and also to have exposure on magnetic materials and dielectric materials.
