Good morning,

The University of Porto SPIE Student Chapter will host another scientific meeting.

This time, the focus is on

**Plasmonic Nanostructures**, with Professor Mário G. Silveirinha from the University of Coimbra.**Date:**January 17th 2014

**Time**: 2:00 p.m.

**Place:**Room 004, FC1, FCUP - Mathematics Department

**Author:**Professor Mário G. Silveirinha

**Title:**"Unconventional Light Wave Oscillations in Plasmonic Nanostructures"

**Abstract:**

In open systems the energy associated with a photonic mode may continuously leak away in the form of a radiated wave, and hence the lifetimes of all natural oscillations are finite. This property is closely related to the problem of instability of the Rutherford atom in classical physics. In this talk, I will theoretically show that in the limit of vanishing material loss plasmonic materials offer the opportunity to have light localization in open bounded systems with infinitely long oscillation lifetimes and no radiation loss.

In the second part of the talk, I will show that when an (uncharged) plasmonic material is set in relative motion with respect to another (uncharged) polarizable body the combined system may be electromagnetically unstable such that if the relative velocity is enforced to remain constant the system may support natural oscillations that grow exponentially with time. This new phenomenon is analogous to the Cherenkov effect, but for uncharged polarizable bodies.

I hope to see you there!
