CSEM component analysis: Analysing the contribution of different components to the HED response in a typical 1D VTI medium

A MATLAB program was built around 1D closed form representations of the radial electrical field in a vertical transverse isotropic (VTI) medium driven by an horizontal electric dipole (HED) in the transverse magnetic (TM) and transverse electric (TE) mode published in Andréis and MacGregor (2008). It is able to compute the contribution of the...

Monitoring and assessing concrete bridges with intelligent techniques

Development of a Two-Dimensional Resonator Design Tool

One of the engineering challenges in high-field MRI is to have a homogeneous distribution of the RF magnetic field inside human tissue. In this project we develop a design tool for a HEM wrist applicator that has the ability to generate a homogeneous magnetic field inside human wrist. By taking into account the dominant RF scattering effects...

Loop-to-Loop Pulsed Electromagnetic Field Signal Transfer in Layered Configurations: Application to Inter-Chip Wireless Communication

This work has been performed as a MSc. graduation project at Delft University of Technology on the topic `Loop-to-loop pulsed electromagnetic field signal transfer in layered configurations - application to inter-chip wireless communication'. The goal of this project was the derivation of an analytic expression for the space-time Green's...

Assessing the MR compatibility of dental retainer wires at 7 tesla

The radio frequent (RF) safety of dental retainer wires during Magnetic Resonance Imaging at 7 tesla has been investigated using electromagnetic simulations and thermal measurements on a phantom model. In the Netherlands up to 40% of the younger adults have such a dental retainer wire, which at the moment is listed as a contraindication for 7 T...

Non-Invasive Electromagnetic Ablation of Female Breast Tumors

Breast cancer is the most common malignant tumor among women today. Available techniques for treating breast cancer often introduce strong side effects. The non-invasive electromagnetic ablation of breast tumors has a lot of potential, because it can provide a quick treatment modality without introducing harmful side effects. In this project we...

Het ontwerp van elektromagneten, spindel en het frame in een zwevende spindelopstelling

Actieve magnetische lagering (AML) is het in positie houden van een roterende spindel. In deze thesis wordt het ontwerp van enkele onderdelen van een vereenvoudigde AML-opstelling uiteen gezet. Het verschil met een conventionele AML-opstelling is dat de spindel slechts in tweedimensionale richting wordt gestabiliseerd en deze niet roteert. De...
