(15A04403) ELECTROMAGNETIC THEORY & TRANSMISSION LINES

Learning Outcomes:

This course provides the foundational education in static electromagnetic fields, and time varying electromagnetic waves. Through lecture, and out-of-class assignments, students are provided learning experiences that enable them to:

• Analyze and solve the problems of electric and magnetic fields that vary with three dimensional spatial co-ordinates as well as with time.
• Become proficient with analytical skills for understanding propagation of electromagnetic waves in different media.
• Understand the concept of transmission lines & their applications.
• Develop technical & writing skills important for effective communication.
• Acquire team-work skills for working effectively in groups.
