Optical nanoantennas have been of great interest recently due to their ability to support a highly efficient, localized surface plasmon resonance and produce significantly enhanced and highly confined electromagnetic fields. Such enhanced local fields have many applications such as ... Read More

As the application of nanoscale structures becomes increasingly commonplace in modern technologies, the comprehensive modelling of the subject has taken centre stage in its understanding. Take the modern application of nanoscale texturing for optical anti-reflectance as an example here; ... Read More

Surface plasmon polaritons are electromagnetic modes excited at the conducting-dielectric interface owing to the resonant interaction between incident photons and free electrons at the conducting surface. Plasmonic resonances confine optical power at subwavelength scales, which allows ... Read More

We present a study of an optofluidic biosensor. The sensor operates in a transmission mode wherein detection is based on a shift in the transmission spectrum caused by the contrast in refractive index between the carrier fluid and the target biomaterial. We study the behavior of the ... Read More

Parametric finite element simulations were performed to study the effect of film thickness, and electrode size on the different impedance parameters for insulating thin films deposited on a conductive substrate. COMSOL Multiphysics® was used to solve the quasi-static form of Maxwell’s ... Read More

Cable gland is a strain relieving device, designed to attach and secure the end of an electrical cable to the equipment. In the event of short-circuit, large current shall pass through cable’s armour to the ground, keeping cable gland and equipment safe. Current weight of industrial ... Read More

The nature of dark matter remains one of the most pressing puzzles in physics. The MAgnetized Disc and Mirror Axion eXperiment (MADMAX) is a dielectric haloscope dedicated to the search for QCD axion dark matter in the mass range of 40 - 400 µeV. The design of the experiment consists of ... Read More

This work explores the implications of wholly random and non-linear nanostructures on electromagnetic wave propagation within a multiphysics simulation environment. Showcased is a way to noticeably bypass the inaccuracies drawn from the linearity dependency of traditional simulation ... Read More

For the development of a Permanent Magnetic Synchronous Machine (PMSM), optimization of design variables, e.g. the size of an air gap, is performed. When applied to optical instruments in space environment, the motor has to be designed for ultra high vacuum (UHV) and cryogenic ... Read More

This paper presents the quasi-TEM two-dimensional (2D) approach for the analysis of multiconductor transmission lines interconnect in single and two-layered dielectric region using the finite element method (FEM). FEM is especially suitable and effective for the computation of ... Read More
