Finite-difference time-domain (FDTD) algorithms are affected by numerical artifacts and noise. In order to obtain better results we propose the use of the principal component analysis based on multivariate statistical techniques. It allows a str[...]![]()

Alda, Javier ; Salgado Remacha, Francisco Javier ; Sánchez Brea, Luis Miguel ; Rico-García, José María ; González, Francisco Javier | IEEE | 2010Polygonal Fresnel zone plates can be configured in a variety of forms depending on the number of sides of the polygon and the number of phase steps used. This contribution deals with some specific polygonal designs that tessellate the plane: tri[...]![]()

Rico-García, José María ; Salgado Remacha, Francisco Javier ; Sánchez Brea, Luis Miguel ; Alda, Javier | SPIE | 2009-06-17Polygonal Fresnel zone plates with a low number of sides have deserved attention in micro and nanoptics, because they can be straightforwardly integrated in photonic devices, and, at the same time, they represent a balance between the high-focus[...]![]()

We demonstrate the capabilities of principal component analysis (PCA) for studying the results of finite-difference time-domain (FDTD) algorithms in simulating photonic crystal microcavities. The spatial-temporal structures provided by PCA are r[...]![]()

López Alonso, José Manuel ; Rico-García, José María ; Alda, Javier | The Egyptian Society of Solid State Science | 2006Finite-Differences Time-Domain (FDTD) algorithms are well established tools of computational electromagnetism. Because of their practical implementation as computer codes, they are affected by many numerical artefact and noise. In order to obtai[...]![]()

We study theoretically the effect of a new type of blocklike positional disorder on the effective electromagnetic properties of one-dimensional chains of resonant, high-permittivity dielectric particles, where particles are arranged into perfect[...]
