[EN] In this work, we develop a new design method based on fast Fourier transform (FFT) for implementing zone plates (ZPs) with bifocal focusing profiles. We show that the FFT of the governing binary sequence provides a discrete sequence of the same

[EN] In this work, we demonstrate the application of Cantor fractal lenses in acoustics. The Cantor Zone Plate (CZP), previously introduced in optics, is designed from a conventional Fresnel Zone Plate (FZP) using a binary sequence governed by the di

[EN] This work analyzes the influence of the distribution of transparent Fresnel regions over the focusing profile of Soret Zone Plates. It is shown that this effect becomes very significant in those fields where directional transducers are employed,

Práctica de Laboratorio: Ondas Guiadas

Autor: Bachiller Martin, Maria Carmen, Fuster Escuder, José Miguel

En este artículo se presenta un resumen de la teoría básica de Propagación de Ondas Guiadas. Es una práctica de aula, ya que el alumno no va a utilizar recursos de laboratorio si no sus propios recursos didácticos: apuntes de clase y libros. Es
