Perfect absorbers have been intensely studied in recent years because of the fundamental physics and application potentials in many areas such as cloaking, detectors or communication [1, 2]. To achieve absorber working in the terahertz (THz) range, various devices composed of noble metal ... En savoir plus
In this work, we design a type of meta-prism which can provide high-efficiency coupling between free space and optical waveguides at infrared frequencies. The meta-prism is composed of an ABA multilayer structure with a fixed total thickness. By varying the filling ratio of the ... En savoir plus
In a diagnostic system small magnetic beads of about 1µm diameter will be moved along a path in a viscose medium due to magnetic field actuators. Specific ligands on the beads will bound to specific samples. If bound, the diameter and mass of the beads rise and the bead movement is ... En savoir plus
Radiofrequency (RF) ablation is a treatment modality that kills unwanted tissue by heat. RF ablation is now the treatment of choice for certain types of cardiac arrhythmia. During RF ablation, an electrode is inserted into, or steered intravascularly to the target tissue region under ... En savoir plus
The study of light scattering by optically resonant nanostructures is a field of growing interest as a result of the rapid progress in nanophotonics in the last decade. Contrary to their plasmonic counterparts, high-index dielectric structures exhibit low optical losses and different ... En savoir plus
Surface Enhanced Raman Scattering (SERS) phenomenon is well known for its detection sensitivity, however, to better understand how it works a better insight needs to be developed on the physics behind the phenomenon. The physical aspects known to produce SERS effect are the use of ... En savoir plus
The underwater electric potential (UEP) signature of naval vessels poses a severe threat as it is detectable by advanced sea mines. The signature depends also on the environment, mainly the water-seabed interface, leading in summary to the total UEP signature. The seabed has a ... En savoir plus
Whispering-gallery mode resonators (WGR) are promising elements for future photonic devices, as they combine ultra-high quality factor with small size and mode volume. Many practical applications of such microresonators, such as ultra-sensitive chemical and biological sensors [1] electro ... En savoir plus
PIR (Passive Infrared) sensor is the most widely used motion sensor for occupancy detection in building automation applications. Normally, only the binary information indicating presence or absence is used. However, an advanced analysis of the PIR sensor analog signal can results in more ... En savoir plus
Introduction: The Gigahertz Transverse Electromagnetic (GTEM) cell is a fundamental tool for calibration purposes and for studies on Electromagnetic Compatibility (EMC), being able to emulate an incident plane wave (TEM mode) on equipment under test in the GHz frequency band. This ... En savoir plus
