Abstract

Plasmonics has opened unforeseen applications due to its sub-wavelength scale control over modes of collective oscillations of free electron gas in solids. This control is only possible due to nano-structuring of the underlying media. I introduce my TeraVolts per meter (TVm⁻¹) plasmonics initiative which promises many tens of TVm⁻¹ fields by relying on nanostructured materials to access a novel class of relativistic plasmonic modes excited as “trailing wake” of intense ultrashort particle bunches. Nanomaterial tubes with a hollow core are critical to mitigate the disruptive effects of collision of the particle beam with the ionic-lattice. Specifically, I present underlying concepts and theoretical model of highly nonlinear surface plasmonic waves. These surface waves are sustained by a train of “crunch-in” surface plasmons with large-scale electron-ion charge-separation which leads to tens of TVm⁻¹ fields. The crunch-in surface plasmons are thus strongly electrostatic unlike other plasmonic modes. Access to unprecedented plasmonic fields opens far-reaching possibilities for transformative impact.
