Optimization of YBCO based superconducting bolometer working above LN2 temperature
This study is focused on the optimization of a- YBa2Cu3O7-x (YBCO) based bolometer working above 77 K. The temperature distribution on the superconductor surface and the temperature profile through the whole system (bolometer plus plate with heaters) were studied at the working point ...

Simulation studies of the MADMAX dielectric haloscope for Dark Matter axion research
The axion is an excellent cold dark matter (CDM) candidate, originally proposed to solve the strong CP problem in strong interactions. A novel method to detect galactic axions is by using their conversion to electromagnetic waves from boundaries between materials of different dielectric ... En savoir plus
An approach to verify the water transport model in organic coatings
The protection of metal surfaces against corrosion is commonly achieved by the application of organic coatings. A dedicated evaluation of those coating systems is strictly necessary before putting them into service. While outdoor test programs are time intensive and accelerated corrosion ... En savoir plus
Electrode design for efficient excitation of vibrational modes in an AlN based PMUT
Piezoelectric micromachined ultrasound transducers (PMUTs) are gaining increasing interest as miniaturized, low-power devices which can be easily integrated with electronic systems for applications such as medical imaging, therapeutic ultrasound, and particle manipulation. This work ... En savoir plus
Hybrid Modeling Approaches for Microwave Heating System Design
One of the advantages of microwave heating of a dielectric material is the direct transfer of electromagnetic energy to the core of the dielectric through interactions between electromagnetic waves and the dielectric, without heating the surrounding elements [1]. For an industrial ... En savoir plus
Time Domain Simulations of Nonlinear Plasma Conductivity by Microwave Inductive Coupling
Exciting plasma in inductive mode is attractive due to the high electron density and the absence of ion interaction with the reactor walls. However, any real system excites plasma at low power in capacitive mode with strong interaction with the walls. The transition from one mode to the ... En savoir plus
CFD modeling of a commercial CVD system and simulation of a CVD deposition process
Seco Tools produces inserts for machining metals. Roughly half the number of inserts Seco Tools produces are coated by Chemical Vapour Deposition (CVD) which extends the inserts lifetime in machining operations significantly. More than 10 000 inserts are coated on trays in each CVD run. ... En savoir plus
Modelling swellable Microneedles for transdermal drug delivery
Swellable microneedles (SMN) have gained a lot of attention to the transport of drugs in the skin. Microneedle swells by absorbing interstitial fluid, causing the loaded drug to transport into the skin without polymer dissolution which reduces the chance of infection and skin irritation. ...

Metamaterial design for ideal solar absorber using multiscale simulations on COMSOL Multi-physics
The renewable energy sector faces challenges in production processes due to geo-economic, and environmental issues. This had led to an increased interest in the use of solar energy as an alternative to fossil fuel based energy sources. In the solar energy field, significant research ... En savoir plus
From the laboratory to the living room: COMSOL as a remote teaching and research tool
At University College London, Applied Analytical Chemistry MSc course, we have used COMSOL Multiphysics as an alternative to laboratory-based student research projects. Use of computational modelling enabled students to complete their research work remotely while gaining experience in ... En savoir plus
