* DEFINITION TRANSVERSE MAGNETIC (TM) WAVES OR E WAVES ** :*

In this case, the component of magnetic field vector **H** lies in the plane transverse to the direction of propagation that is there is no component of **H** along the direction of propagation where as component of electric field vector **E** lies along the direction of propagation.

**Derivation transverse magnetic waves between parallel planes:**

As the direction of propagation is assumed as z-direction, therefore,

H_{z }= 0, E_{z} not equals to 0

By substituting Hz = 0 in equation, we get

H_{x} = 0, E_{y} = 0,and E_{x }not equals to 0, H_{y }not equals to 0

Now write wave equation for free space in term of **H Continue reading “Transverse magnetic waves in parallel planes”**
