A Compact Basis for Reliable Fast Frequency Sweep via the Reduced-Basis Method
PublicationA reliable reduced-order model (ROM) for fast frequency sweep in time-harmonic Maxwell’s equations by means of the reduced-basis method is detailed. Taking frequency as a parameter, the electromagnetic field in microwave circuits does not arbitrarily vary as frequency changes, but evolves on a very low-dimensional manifold. Approximating this low-dimensional manifold by a low dimension subspace, namely, reduced-basis space, gives...

Accelerated simulation-driven design optimisation of compact couplers by means of two-level space mapping
PublicationIn this study, the authors discuss a robust and efficient technique for rapid design of compact couplers. The approach exploits two-level space mapping (SM) correction of an equivalent circuit model of the coupler structure under design. The first SM layer (local correction) is utilised to ensure good matching between the equivalent circuit and the electromagnetic model at the component level. Subsequent global correction allows...

Polarised light pollution on river water surfaces caused by artificial light at night from illuminated bridges and surroundings
PublicationLight is the part of the electromagnetic spectrum visible to the human eye, and such electromagnetic waves can be polarised (Foster et al., 2018) (Supplementary Material). Generally, humans are not able to perceive polarised light, apart from some very specific situations (Haidinger, 1844), while several animals are able to perceive it (Foster et al., 2018). Polarisation can occur when unpolarised light is reflected or transmitted...
