(author)In this article, a novel electrically controlled optical broadband phase shifter (ECO-BPS) is proposed and experimentally investigated for broadband microwave orbital angular momentum (OAM) mode generation. Based on the proposed ECO-BPS and a 17-element circular antenna array, the effect of the phase error on the OAM mode quality is studied by...article 2020

von Benda-Beckmann, A.M. (author), Thomas, L. (author), Tyack, P.L. (author), Ainslie, M.A. (author)Passive acoustic monitoring with widely-dispersed hydrophones has been suggested as a cost-effective method to monitor population densities of echolocating marine mammals. This requires an estimate of the area around each receiver over which vocalizations are detected - the "effective detection area" (EDA). In the absence of auxiliary...article 2018

Phillipson, F. (author)Rolling out a Fibre to the Home (FttH)architecture is very expensive, mainly due to all thetrenching that is labour extensive. In this paper wepresent a method for planning the last mile in FttH in a cost effective way and extend this method for incorporating and minimizing the inconvenience andsocial costs this work brings. To do this, we model...conference paper 2014

de Jong, A.T. (author), Golliard, J. (author)An investigation is performed on the scalability of broadband noise sources from separated flows in internal pipe systems. Broadband sources from for example wellhead chokes, bends and valves can potentially excite subsea manifolds through fluid acoustic coupling and fluid structural coupling. The focus of the current work is evaluation and...conference paper 2013

Berkhoff, A.P. (author)Model errors in adaptive controllers for the reduction of broadband noise and vibrations may lead to unstable systems or increased error signals. Previous research on active structures with small damping has shown that the addition of a low-authority controller which increases damping in the system may lead to improved performance of an adaptive...article 2012

Neto, A. (author), Cavallo, D. (author), Gerini, G. (author)This paper presents a Green's function based procedure to assess edge effects in finite wideband connected arrays. Truncation effects are more severe in broadband arrays, since the inter-element mutual coupling facilitates the propagation of edge-born waves that can become dominant over large portions of the arrays. As a consequence, the overall...conference paper 2011
