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 ... Read More

Simulation studies of the MADMAX dielectric haloscope for Dark Matter axion research

Antonios Gardikiotis1, Stefan Knirck2, Jan Schuette-Engel1
1University of Hamburg, Germany
2Max-Planck-Institut für Physik, Munich, Germany

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 ... Read More

An approach to verify the water transport model in organic coatings

M. Meeusen1
1Vrije Universiteit Brussel, Belgium

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 ... Read More

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 ... Read More

Hybrid Modeling Approaches for Microwave Heating System Design

Junwu Tao1, Tan-Hoa VUONG1, JIngyi Wang1, Li Wu2
1LAPLACE, Toulouse University, Toulouse INP-ENSEEIHT, France
2IAEM, Sichuan University, China

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 ... Read More

Time Domain Simulations of Nonlinear Plasma Conductivity by Microwave Inductive Coupling

Horia-Eugen Porteanu1
1Leibniz-Institut für Höchstfrequenztechnik, Berlin, Germany

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 ... Read More

CFD modeling of a commercial CVD system and simulation of a CVD deposition process

Oscar Alm1, Micael Baudin1
1Seco Tools, Sweden

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. ... Read More

Modelling swellable Microneedles for transdermal drug delivery

Prateek Ranjan Yadav1, Diganta Bhusan Das1, Sudip Pattanayek2
1Loughborough University, Loughborough, UK
2Indian Institute of Technology Delhi, New Delhi, India

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. ...
