Searching for Better Plasmonic Materials

In this post i want to discuss about what’s best material for plasmonic device application except  considering graphene. I want to find a materials with low loss, high confinement and easy fabrication.

Relation between permittivity,refractive index and conductivity in plasmonic elements

Here i want to discuss about relation between permittivity,refractive index and conductivity for plasmonic elements like gold,silver and graphene.

Importance IR light in Biosensor

In biology scientists usually deal with protein, DNA and so on.Other hand biology elements radiate Infrared from themself . So this is very important that we can design IR sensor and apply them in biology fields. Graphene as a miracle material with tunability can be used important candidate  in biosensors.

Importance of impedance matching and coupling mechanism(1)

And older story in microwave and THz  or higher frequency range is finding a way that we have high effieceincy coupling. So i will discuss about mechanism coupling and phase and impedance matching.
