## Homework Statement

A

**half-wave plate**is put between an

**horizontal polarizer**and a

**vertical analyzer**, so we have extinction.

If the anylizer is rotated clockwise an angle

*Theta*, Which angle do we have to ratate the polarizer to keep the extinction of the light?

## Homework Equations

The Jones matrix related are

Vertical analyzer

(0 0

0 1)

Horizontal polarizer

(1 0

0 1)

Half-wave plate

(1 0

0 -1)

## The Attempt at a Solution

If we call the previous matrix A, B and C respectively, we can do A'·B·C=(0 0 0 0), where A' is the rotated A matrix, I mean, [tex]A' = R^{-1}AR[/tex] where R is the matrix of rotation,

R= (cos t sin t

-sin t cost)

(t= theta)
