Abstract

See full text

A device configured for radiating a focused electromagnetic beam is proposed. Such device comprises: —a first (101) and a second (102) part having respectively a second n2 and third n3 refractive index and a first W1 and second W2; —a first contact area (100e1) intended to be between a host medium having a first refractive index n1 and in which the micro or nanoparticles are intended to be trapped or moved by a focused electromagnetic beam radiated by the device; —a second contact area (100e2) between the first part and the second part; and —a third contact area (100e3) intended to be between the second part and the host medium. The focused electromagnetic beam results from a combination of at least two beams among a first (NJ1), a second (NJ2) and a third (NJ3) jet beams radiated respectively by the first, second and third contact areas when an incoming electromagnetic wave (IEM) illuminates the device. The device is configured for having a direction of propagation of the focused electromagnetic beam tilted in respect of a direction of propagation of the incoming electromagnetic wave.
