Focusing the electromagnetic field to 10−6 λ for ultra-high enhancement of field-matter interaction

Focusing the electromagnetic field to 10−6 λ for ultra-high enhancement of field-matter interaction

Subwavelength focusing of electromagnetic fields often uses evanescent waves and nanostructures to aid confinement. Here, the authors localize a microwave field to 6 orders of magnitude smaller than the wavelength, by coupling to confined electron oscillations in a hybrid nanowire-bowtie antenna.
