Loss compensation by gain and spasing.
We present a theory of the effective dielectric response of metamaterials containing gain. We demonstrate analytically that the conditions of spaser generation and the full loss compensation in a dense resonant plasmonic-gain metamaterial are identical. Consequently, attempting the full compensation or overcompensation of losses by gain will lead to an instability and a transition to a spaser s...
متن کاملEffect of Lossy Earth on Antenna Gain
The effect of lossy earth on the far fi eld gain of antennas with finite s ize metal ground planes has been investigated experimen tally. Gain measurements were made of several antennas and their associated ground planes mounted both flu sh with the surface o f the ear th and far removed from the earth. It was found that for the ground plane sizes used in this study the gains for the two situat...
متن کاملFuzzy gain scheduling of PID controller for stiction compensation in pneumatic control valve
Inherent nonlinearities like, deadband, stiction and hysteresis in control valves degenerate plant performance. Valve stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve stiction is essential to maintain scheduling. For industrial scenarios, loss of execution due to nonlinearity in control valves is an imperative issue that should be t...
متن کاملCompensation of loss in propagating surface plasmon polariton by gain in adjacent dielectric medium.
We report the suppression of loss of surface plasmon polariton propagating at the interface between silver film and optically pumped polymer with dye. The large magnitude of the effect enables a variety of applications of 'active' nanoplasmonics. The experimental study is accompanied by the analytical description of the phenomenon. In particular, we resolve the controversy regarding the directi...
متن کاملComment on "Spaser action, loss compensation, and stability in plasmonic systems with gain".
We demonstrate that the conditions of spaser generation and the full loss compensation in a dense resonant plasmonic-gain medium (metamaterial) are identical. Consequently, attempting the full compensation or overcompensation of losses by gain will lead to instability and a transition to a spaser state. This will limit (clamp) the inversion and lead to the limitation on the maximum loss compens...
