Snell law for low refractive index materials

I was reading on my lectures slides what will happen if there if there is an incident ray on the interface between air and a lower refractive index medium (it is a special case which exists only in ...

What is the difference between ordinary-spacial cloaking and spacetime cloaking?

I am unsure of what are the differences between space time cloaking and spacial cloaking, as any event can be hidden from a viewer using spatial cloaking for however long the cloaking is activated, ...

Strange material, Bydrogen

Let's take a hypothetical scenario in which you manage to make a meta material in which the bulk of the mass is made of by a central negative nucleus and that has a single spin 1 boson whizzing around ...

FDTD simulations for metamaterials and complex refractive index

I have designed a working FDTD code to simulate electromagnetic wave propagation using Yee's algorithm. I have been able to place materials such as glass slabs, etc which have positive and real ...

What is a Material Called that Translates the Image of a Touching Object's Surface?

What is the name of a material that moves light through it in such a way that it appears that the surface of an object has translated through the material? Also, what is an example of this type of ...

Metamaterial/Optics Book Recommendation

I recently won a prize at my school for physics (£25) for which they ask that we spend some money they have given us on a book with which they can present us during an assembly. Given that over the ...

Would a metamaterial change its properties if one used different isotopes of an atom in its construction?

Given one had a metamaterial of a given type, containing some limited types of elements... if one were to use just one isotope of a given element (assuming it had more than one) in the construction ...

Perfect reflection with metamaterials with indices of refraction less than one

Total internal reflection is used to send light signals long distances in fiber-optic cables. If the cable is shaped into a ring, the light will run in a circle until its intensity dwindles due to ...
