Circular Electromagnetic Wave Polarizer

An more general elliptical (circular is a special case where Ex=Ez) polarized Electromagnetic Wave travels from left to right.

After passing through the first polarizer, the Electromagnetic Wave now is linearly polarized along the direction of the polarizer, θ₁ .This is usually how linearly polarized light is formed.

After passing through the second polarizer, the Electromagnetic Wave now is further linearly polarized along the direction of the second polarizer, θ₂. If θ₂=θ₁, the light passes through without any difference. If θ₂-θ₁=90 degree, the light passes through is completely blocked.

Visualization

Electric Field is represented as Red color segments

Polarizer 1 is Orange color

Polarizer 2 is Green color

Controls

You can modify:

θ₁ is the angle of the first polarizer

θ₂ is the angle of the second polarizer
