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 ...

List of complex refractive indices for various frequencies and various materials

I want a list of refractive index values for various materials (or even a single material) for various frequencies / wavelengths (I need this specifically for the micro wave - radio wave regions of ...

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 ...

Resonant frequency of Split Ring Resonator (SRR)

I am working on circular and square split ring resonator design as part of my thesis. I wrote a Matlab code to calculate SRR resonant frequency but I am not getting the same answer of any published ...

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 ...

Induced EMF in metamaterial

I am reading JB Pendry's original paper on metamaterials (Magnetism from Conductors, and Enhanced Non-Linear Phenomena) and I am really having some trouble understanding just a few of his mathematical ...

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 ...
