Mexico will be electing a new president on 1 July. No matter who wins, there will be little change in the deep political crisis affecting the country. This is the message given by José Carlos G. Aguiar, university lecturer in Latin American studies.

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…
