The main objective of this course is to introduce basic concepts of electromagnetics and establish the foundation of understanding various electromagnetic theories, which are indispensable for many modern electrical and electronic devices of power and energy systems, telecommunications, computing, and other technologies.
The course aims to develop vector calculus, phasor, and differential equation based mathematical skills for solving electromagnetic field and wave related problems of practical usage.
Students will become familiar with electromagnetic applications that are used in the designs and implementations of electrical and electronic systems and modern wireless communications systems.
Thus, the course aims to give students the necessary background for the design and analysis of both low frequency electrical devices and high frequency electronic components.
Basics of vector calculus and coordinate geometry.

Class participation and attendance will be recorded in every class. Participation and attendance for the students may be considered in case the student could not attend the class due to a valid reason (power failure, internet problem, device problem, health problem, etc.). The student has to inform the teacher over email in case of such occurrences. A maximum of three (03) such missed classes can be considered for this course
Four nos. of tests (Quiz, Assignment, Viva and Presentation) will be taken and best 3 nos. will be counted.
A comprehensive term final examination will be held at the end of the Term following the guideline of academic Council.
Homework Assignment and Quizzes (continuous assessment) 20%
Final Examination (3 hours) 70%
