Question

Consider the definition of plane waves. Can they exist in a very high-loss material? If so, what are the differences between plane waves in low- and high-loss materials?

Expert Solution

Step 1

Answer is:

Consider the definition of plane waves.

Plane waves are those which have uniform direction and magnitude in a given orientation.
Electromagnetic waves are plane waves having constant electric and magnetic field so we will take their example for answering this question.
Plane wave provides a uniform and fundamental concept for understanding the electromagnetics and Maxwell's equations.
The basic thing to understand in the wave motion is that The electric field's time derivative equals electric field space derivative and magnetic field's time derivative equals the electric field's space derivative.
To produce the time-varying electric and magnetic fields it is very necessary that both electric and magnetic fields co-exist.
