Internships Summer 2017/18
Proposed Project Title:
Inkjet printed frequency selective surfaces for smart wireless communications
Dr G Conway & Dr R Cahill
The purpose of the proposed project is to develop a unique and practical disruptive technology which will enable wireless communications systems to be electromagnetically decoupled from their physical surroundings.
This well-known problem, which has never been solved, is responsible for reducing the reliability and efficiency and degrading the polarisation purity and beam coverage of many modern communications systems, particularly those that employ low gain antennas. These include on-body sensors, vehicular transceivers and many satellite payload instruments.
The aim of the internship is to investigate the design and construction of ink-jet printed ultra-thin microwave absorbing material which is composed of a metal backed array of resistively loaded loops. This can be deployed to provide an electromagnetic barrier between the antenna and host platform. In this work the relationship between the resistance of the material and the digital settings of the printer and conductive ink/solvent composition will be investigated experimentally
- Study the design and operation of resistive Frequency Selective Surface (FSS) absorbing material
- Design a test device using CST microwave studio software package.
- Experimentally vary the ink-jet printer parameters, digital settings, solvent/ink composition, ink thickness etc
- Measure the spectral transmission response of the FSS structures
- Match the simulated and experimental data to obtain the resistance of the loop elements
- Write up findings in a report
The scheme is open to all EEECS Undergraduates (apart from students on the BIT degree pathway and students who are due to graduate this summer)
Each internship will last between 6-8 weeks and will pay a weekly stipend of £200.
Accommodation and travel costs are not provided under this scheme.
Start date: 24 July 2017
Duration: Negotiable (6 to 8 weeks)
Location: Centre for Wireless Innovation, ECIT Institute, Queens Road, Belfast BT3 9DT
