What is inhomogeneous media? (Electromagnetic Waves)

AI Thread Summary
Inhomogeneous media are characterized by varying properties at different points, unlike homogeneous media where properties remain constant throughout. The refractive index is a key property that can change spatially in inhomogeneous media, affecting how electromagnetic waves propagate. Understanding these differences is crucial in fields like optics, where the behavior of light is influenced by the medium's characteristics. The distinction between homogeneous and inhomogeneous media is essential for accurate modeling and analysis in electromagnetic theory. This knowledge is vital for applications in optics and telecommunications.

I see this term a lot. What is the different between homogeneous and inhomogenous? What properties are different?

Thanks

For an homogenous medium all properties are the same at any point (or at least the properties in which you are interested - you have to be certain that any properties that differ have no effect on what you are considering)
 
In connection with electromagnetic waves in the optical domain, it is the refractive index which changes with place in an inhomogeneous medium.

Thread 'How to picture the vector potential?'

Susskind (in The Theoretical Minimum, volume 1, pages 203-205) writes the Lagrangian for the magnetic field as ##L=\frac m 2(\dot x^2+\dot y^2 + \dot z^2)+ \frac e c (\dot x A_x +\dot y A_y +\dot z A_z)## and then calculates ##\dot p_x =ma_x + \frac e c \frac d {dt} A_x=ma_x + \frac e c(\frac {\partial A_x} {\partial x}\dot x + \frac {\partial A_x} {\partial y}\dot y + \frac {\partial A_x} {\partial z}\dot z)##. I have problems with the last step. I might have written ##\frac {dA_x} {dt}...

Thread 'Griffith, Electrodynamics, 4th Edition, Example 4.8. (Second part)'

I am reading the Griffith, Electrodynamics book, 4th edition, Example 4.8. I want to understand some issues more correctly. It's a little bit difficult to understand now. > Example 4.8. Suppose the entire region below the plane ##z=0## in Fig. 4.28 is filled with uniform linear dielectric material of susceptibility ##\chi_e##. Calculate the force on a point charge ##q## situated a distance ##d## above the origin. In the page 196, in the first paragraph, the author argues as follows ...
