Overview
(4 years, fully funded)
At the Telecommunication Engineering Group, CTIT Research Institute, University of Twente, Enschede, The Netherlands
The Telecommunication Engineering and Electromagnetic Compatibility (EMC) research group at the University of Twente is part of the multidisciplinary research institute Centre for Telematics and Information Technology (CTIT). The group is within the Department of Electrical Engineering, Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS). The department is one of three academic institutions in the discipline of Electrical Engineering in the Netherlands.
Project: Random Electromagnetic Field Coupling into Cables
Problem description
Electromagnetic fields inside enclosed environment, i.e. a car, fuselage, bus, either caused by equipment (unwanted emission) or wanted emissions due to mobile communication equipment, or fields penetrating such an enclosed environment (due to leakage or through windows) will resonate.
A part of the work is dedicated to the resonances inside a (semi) enclosed environment resulting in a higher field strength than originally estimated. As a result, there is a higher risk of interference.
This activity assumes a non-deterministic behavior of the fields in and around such enclosed environments. With respect to Electromagnetic Interference (EMI), the main focus is on the risk of EMI in the tail of a probability function, which means in theory that many simulations have to be performed. The objective is to find the critical parameters, i.e. which parameters have a main influence on the extreme field strengths.
Another part of the work is coupling of resonating electromagnetic fields into cables. In practical systems there is a statistical spread in many parameters e.g. in position of wires, size of small apertures, material properties etc. Exploring the parameters space to establish the statistics of the response by repeated computation is very time consuming requiring thousands of computations. Alternative approaches where only a small number of computations is required will be explored.
Research method
Determine the validity of the central limit theorem, resulting in the chi-square (Rayleigh) distribution for enclosed environments, in case the environment is not completely resonant or not completely enclosed. Where are the limits in theory, taking actual structures into account, and what is the impact on fields. Also investigate the impact of fields very near to metal structures by varying the boundary conditions.
Investigation on variational parameters to be included in traditional transmission line models. Sensitivity analysis methods, investigation on 'Monte-Carlo' analysis techniques as used in circuit simulations, Importance Sampling as well as other techniques are possible candidates.
Entry requirements
Applications are invited for a fully funded four-year PhD researcher in the Telecommunication Engineering and Electromagnetic Compatibility (EMC) research group. The ideal candidate should possess, or expect to obtain, an MSc degree in a discipline relevant to the proposed research. He or she should have a demonstrable ability to work well in a team, have intellectual curiosity, as well as knowledge of one or more of the topics described above.
Funding/Salary
A four-year PhD researcher opportunity is available immediately to carry out research into the exciting and growing field of electromagnetic compatibility. The successful candidate will be provided with excellent opportunities for gaining experience, for building a career in this prospective research field, and for extending his/her knowledge via international exchange programs, participation in national and international conferences and workshops, and global visits to prestigious research institutes and universities.
The award will provide a monthly gross salary for the successful candidate, in accordance with the Dutch universities collective labour agreement, within the range of EURO 2042, for the first year, to EURO 2612 for the fourth year.
