Transmission Lines And Electromagnetic Waves Nptel

Once you understand how waves move in a "guided" wire, the course expands into in free space.

, governed by Maxwell’s equations, describes how electric and magnetic fields interact. It treats circuits as "distributed" systems.

NPTEL does not shy away from differential equations, but the instructors break down the solution to the telegrapher’s equations into clear steps:
