Rotary penetration drag of surface plasmon polaritons at atomic and nano-composite media
TLDR
In this paper, surface plasmon polaritons at the interface of cesium atomic medium and silver-silica nano-composite were investigated at the intersection of the two materials.Abstract:
Surface plasmon polaritons are investigated at the interface of cesium atomic medium and silver-silica nano-composite. The polaritons rotary drag at the propagation length and penetration depth is significantly modified. The ratio of the wavelengths of surface plasmon polaritons and the free space electromagnetic waves are nearly 0.5810. The group velocity of plasmon polaritons is higher than the speed of light and is ranging from $$-6\times 10^9$$
to $$1\times 10^{10}$$
which shows higher superluminality in a small propagation length. The penetration depths of polaritons in cesium and nano-composite are $$1.5\times 10^{-10}m$$
and $$2\times 10^{-7}m$$
and vary with strength of the control fields. The rotary plasmon polaritons drag is in the rang of $$\pm 50$$
to $$\pm 60$$
nano radian at the propagation length of polaritons. The rotary plasmon polartions drag at the penetration depths of the atomic and the silver nano-composite media is noted in the range of $$\pm 10$$
atto radian and $$\pm 10$$
femto radian respectively. The results may find applications in modifying the sensor coding technology.read more
