Ideal surface for a perfect lens
in this physics lecture, on slide 15-16, it is found that the ideal surface for a perfect lens (which maps a plane wavefront into a perfect spherical wavefront, i.e. which makes focus all input ...

What formalism is used to model thin film optical coatings that function across a range of angles of incident light?
Thin film optical coatings [0] are atomically/molecularly thin layers of material applied to a substrate with the intent of affecting the optical properties of the substrate. For example, magnesium ...

Birefringence in uniaxial materials
In linear optics, when treating anisotropic uniaxial materials we get the frensel equation
this equation gives us two solution for n. My problem is that according to Snell's law, if I have two ...

Enhancing of EM waves through a materal or waveguide
I'm wondering whether there are materials for which an incident EM wave would behave as $\vec E(z,t)=\vec E_0 e^{\kappa z}e^{i(kz-\omega t)}$ where z describes how far from the surface the fields are ...

Is there a (cheap) optical resonance demonstration using visible light?
I'm looking for a impressive, inexpensive lecture demonstration of optical standing wave resonance. Preferably visible light. Can anyone suggest such a demo?
