Abstract
A device () is proposed comprising a first part () of a first material having a first refractive index nand a second part () of a second material having a second refractive index nhigher than n. Such device further comprises at least one contact area () in between the first and second parts, radiating an outgoing electromagnetic wave () when the device is illuminated by an incoming electromagnetic wave (). A projection of the at least one contact area along a direction of propagation of the incoming electromagnetic wave has a non-vanishing height lower than 1.2 times a critical height equal to a wavelength in vacuum of the incoming electromagnetic wave divided by the difference between the second refractive index nand the first refractive index n
