Enhanced Surface Plasmon Polariton Propagation Induced by Active Dielectrics

M. Mattheakis[1], C. Athanasopoulos[1], G. P. Tsironis[1]
[1]University of Crete, Heraklion, Greece

We present numerical simulations for the propagation of surface plasmon polaritons in a dielectric-metal-dielectric waveguide using COMSOL Multiphysics® software. We show that the use of an active dielectric with gain that compensates metal absorption losses enhances substantially ... En savoir plus

Plasmonics of Nano-Gaps

T. Hutter[1], S. Mahajan[2], S. R. Elliott[1]
[1]University of Cambridge, Cambridge, UK
[2]University of Southampton, Southampton, UK

Plasmons, i.e. the collective oscillations of electrons in a metallic nano-structure, lead to strong light scattering, absorption and an enhancement of the local electromagnetic field. In this work, the local electric-field enhancement in a system of dielectric nanoparticles placed ... En savoir plus

Biological Effects of Microwave Radiation

S. Kumari[1], S. Raghavan[1]
[1]National Institute of Technology Tiruchirappalli, Tiruchirappalli, Tamil Nadu, India

Microwave technology has provided with many exciting new therapeutic and diagnostic methods. Frequencies from RF as low as 400 kHz through microwave frequencies as high as 10 GHz are presently used for therapeutic applications in areas such as cardiology, urology, surgery, ophthalmology, ...
