The Operation of an Important "Light Guiding Device"

Introduction:

Device schematic:

Two particular device examples:

Deflection as function of n2 and b1 (b2= b1) with fixed at 30° -- i.e. a slab oriented at
an angle b1 wrt the direction orthogonal to the horizontal axis.

 

Deflection as function of n2 and b1 (b2= b1) with fixed at 30° -- i.e. a slab oriented at
an angle b1 wrt the direction orthogonal to the horizontal axis.

Note the general result that there is no deviation when the
slab is homogeneous -- i.e. when  n2 = n1

 

Deflection as function of n2 and b1 (b2= b1) with fixed at 0° -- i.e. a slab oriented at
an angle b1 wrt the direction orthogonal to the horizontal axis and the interface parallel to that direction.


 

Deflection as function of n2 and b2 with b1 and fixed:
