Science classifies light by wavelength rather than colour. As such, colours such as yellow and red correspond to wavelengths of around 570 and 620 nm, respectively. Unlike visible colours, wavelength is also applicable to describe radiation invisible to the human eye. Radiation with wavelengths longer than that of red light is called infrared light. Infrared technology is very relevant for applications where visible light cannot be used, such ...
Surface acoustic waves on PZT thin films for particle manipulation Ghent University
Piezoelectric materials are able to convert an applied electrical signal into mechanical strain and stress. By using an electrical signal with a certain frequency, it is possible to generate an acoustic signal with the same frequency. Specially designed devices are able to generate the acoustic signals along the surface of a substrate. The generated Surface Acoustic Waves (SAWs) propagate on top of this piezoelectric substrate. Devices using ...
ORINoCO: Optical Receivers IN standard CmOs Ghent University
Optical communication is an interesting alternative for communication over a copper wire when
speed, weight and electromagnetic immunity are considered important. If the cost of going optical
instead of staying electrical were not so high, it would probably be used in a lot more applications.
Therefore, in order to make this possible, the goal of this project is to investigate a novel concept of
implementing a full optical ...

Exploring the physical principles of electromagnetic energy harvesting in GHz and THz metamaterials. KU Leuven
Metamaterials, consisting of periodically arranged sub-wavelength structures, exhibit extraordinary electromagnetic (EM) properties that can be used for a wide range of applications such as subdiffraction imaging, EM induced transparency, and invisible cloaking. Recently, metamaterial absorbers get a lot of attention as ambient EM energy harvester to absorb, for example, unused energy from wireless hotspots, and convert it into electric ...
Characterization and minimization of human RF-EMF exposure in realistic urban environments Ghent University
As telecommunications networks evolve to cope with ever-increasing user demands, so does our
exposure induced by radiofrequency (RF) electromagnetic fields (EMF). Though in most countries
legislation through science-based limits restrict this exposure, our methods to accurately
characterize it in our everyday environments are lacking in efficiency and are based on strict
assumptions. This research proposal aims in the ...
Biomimetic optical nanostructures Ghent University
Arrangements of material at the nanometer scale produce a dazzling array of colors, ranging from
ultra violet to red, without pigments. These so-called structural colors are particularly distinctive in
birds, which can produce non-iridescent colors (such as the blues of blue tits) using matrices of
keratin and air, or iridescent colors (such as the flashy colors of hummingbirds) using arrays of
