Welcome to The Green Village

A sustainable world can only be achieved by an open collaboration between science, business and the public. That is why we create the Green Village: an innovative, lively, interactive and challenging environment where entrepreneurs, innovators, companies, artists, teachers and visitors can meet, work and play to develop, apply and experience...

Wireless digital information transfer: Modelling, prediction and assessment

The loop-to-loop pulsed electromagnetic field wireless signal transfer is investigated with a view on its application in wireless digital information transfer. Closed-form expressions are derived for the emitted magnetic field and for the open-circuit voltage of the receiving loop in dependence on the mutual orientation of the loops and the...

Ensemble methods for large scale inverse problems

Variational data assimilation, also sometimes simply called the ‘adjoint method’, is used very often for large scale model calibration problems. Using the available data, the uncertain parameters in the model are identified by minimizing a certain cost function that measures the difference between the model results and the data. A variational...

THz Leaky Lens Antenna integrated with Kinetic Inductance Detectors

This contribution presents the fabrication and measurements of the leaky lens antenna integrated with a cryogenically cooled Kinetic Inductance Detector, in order to achieve an ultra sensitive THz receivers over a bandwidth ranging from 0.15GHz to 1.5 THz. The system has been manufactured and characterized in terms of power efficiency, and...

Pulsed Electromagnetic Fields: Their Potentialities, Computation and Evaluation. Proceedings of the Workshop March 18–19, 2013, Delft, the Netherlands

This book contains the contributions to the workshop Pulsed Electromagnetic Fields: Their Potentialities, Computation and Evaluation. The papers included in this volume cover a very broad range, from the physical and mathematical foundations up to operational systems making use of the potentialities arising from the use of pulsed electromagnetic...

Generalized-ray theory for electromagnetic fields in layered media

Generalized-ray theory for time-domain electromagnetic fields in a horizontally layered medium is developed. After introducing appropriate integral transformations and source-type field representations in vertically inhomogeneous media, the solution is written out in terms of generalized ray constituents whose space-time counterparts are...

Array-structure theory of Maxwell wavefields in affine (3 + 1)-spacetime: An overview

An array-structure theory of Maxwell wavefields in affine (3 + 1)-spacetime is presented. The structure is designed to supersede the conventional Gibbs vector calculus and Heaviside vectorial Maxwell equations formulations, deviates from the Einstein view on spacetime as having a metrical structure (with the, non-definite, Lorentz metric), and...
