Q. Fang, Identifiability Analysis of a Wind Generation Unit Model Using Global Sensitivity Analysis, 3rd March 2016.

  Abstract: This seminar presents a parameter identifiability method based on the Global Sensitivity Analysis (GSA), and its application in parameter estimation of a wind generation unit model. The GSA determines which model parameters will effect observations that are used in the parameter estimation procedure. Parameters with negligible impact on the observations are not identifiable. […]

C. Zou, Mechanically tunable dielectric resonator metasurface at visible frequencies, 25th February 2016.

  Abstract: Recent years have seen significant advances in light manipulation with ultrathin planar metasurfaces. The underlying mechanism is spatially varying phase discontinuity introduced by subwavelength resonators. Metallic resonators have commonly been used as a core component in metasurfaces so far. Recently we have shown that it is possible to replace metallic resonators with dielectric […]

A. Ebrahimi, Miniaturised-elements frequency selective surfaces for microwave and terahertz applications,18th February 2016.

  Abstract: Frequency selective surfaces (FSSs) are usually formed by two-dimensional periodic arrangement of metallic elements on a dielectric substrate. Based on the geometry and arrangement of the metallic unit cell, the array might show different functionalities such as bandpass or bandstop spatial filter. The FSS functionality is mainly determined by its unit cell geometry […]

G. Stamatescu, Track-Before-Detect with Hidden Reciprocal Chains, 4th February 2016

  Abstract: Track-before-detect (TBD) is a statistical hypothesis testing technique that tests for the presence or otherwise, of a dynamic target using noisy and/or incomplete sensor measurements. Rather than making a detection decision directly from the observations, then handing relevant detection information to a model based tracker, TBD methods reverse this order of processing by […]

C. Zou, Resonance breakdown of dielectric resonator antennas on metallic substrates at visible frequencies, 17th December 2015.

  Abstract: Dielectric resonators have seen increasing applications in optical metamaterial designs. The ability of nanoscale Dielectric Resonator Antennas (DRAs) to support electric and magnetic resonances at visible frequencies is critical for their efficient light manipulation, which leads to promising applications such as sensing, imaging, field enhancement, and integrated optics. This talk discusses the resonance […]

Q. Fang, A Global Optimization Framework for Parameter Estimation of a Wind Generation Unit Model, 26th November 2015.

  Abstract: This research purposes a global optimization method that could be applied in parameter estimation of wind generation unit model. When complex nonlinear models, like a wind generation unit model are used, the parameter estimation based on local optimization methods, such as nonlinear least squares method or Newton’s method, may not be able to […]
