*DEFINITION* *TRANSVERSE ELECTRIC (TE) WAVES OR H WAVES** IN PARALLEL PLANES:*

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

**Derivation of transverse electric waves in parallel planes:**

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

E_{z} = 0 and H_{z} is not equal to 0

Now by substituting E_{z} = 0 in equation (8) of article “waves between parallel planes”, we get

E_{x}= 0 and H_{y} = 0 and

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

Now write wave equations for free space in terms of E

Ñ^{2}E =g^{2}_{g}**E**

= -w^{2}με**E** (because g^{2}_{g} = (jwμ) (σ + jwε) As σ =0(from assumption (c) of article “waves between parallel planes” => g^{2}_{g} =-w^{2}με)

Or d^{2}E/dx^{2} + d^{2}E/dy^{2} + d^{2}E/dz^{2} = -w^{2}με**E**

For the y component, the wave equation will become Continue reading “Transverse electric waves”
