Martínez Herrero, Rosario ; Maluenda, David ; Juvells, Ignasi ; Carnicer, Artur | IEEE Computer Society | 2019-02-18According to intensity consideration along the propagation axis, we derived mathematical conditions for a family of modulating functions able to produce needles of arbitrary length, sub-wavelength width and almost constant irradiance. These func[...]texto impreso
Maluenda, David ; Juvells, Ignasi ; Martínez Herrero, Rosario ; Carnicer, Artur | Optical Society American | 2019-05-15Optical needles produced by means of diffractive technology might display limited quality and uniformity. It has been suggested that the bulky optical elements present on these setups can be responsible of such behavior. In particular, issues su[...]texto impreso
Martínez Herrero, Rosario ; Maluenda, David ; Juvells, Ignasi ; Carnicer, Artur | Nature Publishing Group | 2017-02-13Polarisers are one of the most widely used devices in optical set-ups. They are commonly used with paraxial beams that propagate in the normal direction of the polariser plane. Nevertheless, the conventional projection character of these devices[...]texto impreso
Martínez Herrero, Rosario ; Carnicer, Artur ; Juvells, Ignasi ; Sanz Ortiz, Ángel Santiago | The Optical Society Of America | 2020-09-29In the analysis of the on-axis intensity for a highly focused optical field, it is highly desirable to deal with effective relations aimed at characterizing the field behavior in a rather simple fashion. Here, a novel and adequate measure for th[...]
