he fi eld of plasmonics has grown dramatically over the
past decade, and still continues growing towards new
directions enabling new fundamental science and device tech-nologies. Research in this area explores how electromagnetic
fi elds can be confi ned over dimensions smaller than the
wavelength. It is based on interaction processes between elec-tromagnetic radiation and conduction electrons at metallic
interfaces or in small metallic nanostructures.(he fi eld of plasmonics has grown dramatically over the past decade, and still continues growing towards new directions enabling new fundamental science and device tech-nologies.

FUZZY_ACDCSYSTEMS
This paper discusses the impact of HVDC on
Power System Stability and proposes a new control mechanism
based on Fuzzy set theory to augment dynamic performance of
a multi-machine power system. To have good damping
characteristics over a wide range of operating conditions,
deviations in speed and acceleration of the machines are chosen
as the input signals to the fuzzy controller. These input signals
are first characterized by a set of linguistic variables using fuzzy
set notations .The fuzzy relation matrix allows a set of fuzzy
logic operations that are performed on controller inputs to
obtain the desired output. The effectiveness of the proposed
controller is demonstrated by a multi-machine system example.
The performance of this fuzzy controller, in comparison to the
conventional fixed gain controller, demonstrates the efficacy of
this new fuzzy PID controller.
