  15. Lab Structure Could be…..??? • MATLAB based labs to be conducted on Electromagnetic Fundamentals Concepts • Vector algebra • Coordinates system and transformations • Electric field Simulation • Electric potential Simulation • Magnetic field Simulation • Divergence, Curl, Gradient Simulations • Bio-Savart Law and Ampere’s Law Simulations Introduction 15

  16. Grading Matters • Probable Grading Criterion • Quizzes (best of 5 to be selected): 10% • Home Assignments: 5% • Lab Assignments: 10% • Semester Project 5% • One Hour Tests (6th and 13th week): 30% • Final Exams (20th week): 40% Introduction 16

  17. Some practical issues… • Attendance • Student with less then 75% will NOT be allowed to sit in the OHTs and Final exam • Attendence will be taken within 2-3 mins of commencement of class and doors would be closed. • Punctuality to be maintained for lectures/lab sessions. • Mobile phones to be switched off. • No late submission of assignments or /copying cheating of any type shall be allowed in any case. • Assignment submission to be done before commencement of next class. • No activity of ill discipline (talking , disturbing the class) to be tolerated. Introduction 17

  18. Some practical issues…contd! • In case of absence, you are responsible of getting to know about assigns/lecture notes/announcements missed. • Convey your collective class problems through your CR • To deal with any sort of individual course related problems, contact me: • In class • Through email Introduction 18

  19. Electrical & Communication Engineering Model Information System Energy Model 2: TX Line Theory Model 3: Field Theory DSP, COMM CONTROL Systems Model 1: Circuit Theory EM Advance Courses EMT NETWORKS Introduction 19

  20. Electromagnetics • The study of effect(electric and magnetic fields) of charges at rest and charges in motion. • The Electromagnetic force is one of the four known fundamental forces of nature • All theory of electrical engineering is based on electromagnetics Introduction 20

  21. Something to think about! Fundamental Limits Information System Energy Shannon’s Theorem Nyquist Stability Criterion Maxwell’s Equations Fundamental laws of classical electromagnetics Introduction 21

  22. Why study electromagnetics? • Wireless communications systems require antennas • To better understand modern communications and computer systems. • To be able to design and analyze electromagnetics- based devices Introduction 22

  23. Why Electromagnetics is difficult? • Because Electric and Magnetic Fields • are three-dimensional • are vectors • vary in space as well as time • are governed by PDEs • As a result • Solution of electromagnetics problems requires a high level of abstract thinking – which is an ability to think three dimensionally in space.It is not possible to solve them by finding the right formula in which to plug the numbers. • Students must develop a deep physical understanding of wave propagation mechanisms where math becomes a powerful tool rather than a crutch Introduction 23

  24. Jobs in Electromagnetics Wireless Communication (Motorola, Mobilink, Ufone, Siemens,Nokia, Samsung, etc.) Integrated Circuits and Complex Computing/Communication Systems (Intel, IBM, AMD, etc.) High Performance Communication and Radar Systems (Northrop Grumman, BAE, Lockheed Martin, Boeing, Rockwell Collins, Raytheon, etc.) National Laboratories (SUPARCO, Air Weapons Complex, NASCOM, National Defence Complex, etc.) Computational Electromagnetics R&D Introduction 24
