Terahertz Antenna Design for Biomedical Applications

(supervisor: Syeda Fizzah Jilani)

Nature of project: experimental, experimental

Available to students on full-time physics degree schemes or joint students.

Project description and methodology

Terahertz (THz) spectrum has received huge attention for characterisation, imaging and detection. The non-ionising nature of THz waves and high sensitivity to soft body tissues makes it suitable for medical diagnosis and treatment for both in vivo and ex vivo analysis [1]. THz antenna is a core element of a THz imaging system for screening and diagnostics and has a critical role in both impedance matching and power source [2]. In such applications, a compact and highly-directive THz antenna is required with preferably on-chip fabrication to obtain large depth-of-field for good image resolution. 

The project has been specifically designed for an in-depth literature survey of the advantages and scope of THz antennas for biomedical applications. In addition, the student will design a THz antenna in a software and analyse its performance attributes. The analysis could be further extended to on-body characterisation of the antenna properties in the simulation software based on time availability.

The project is purely literature and simulation based and can be completed at home using remote access by means of a standard PC or laptop.

A successful project will develop beyond the above in one/some of the following directions:
When deciding how far you can lead your project, the available time is critically important. It is preferable to focus on key milestones first and complete these well than struggling with many and not achieving enough results at the end. A comprehensive analysis based on simulation is a major requirement. Though a potential to publish a conference paper will be decided later-on based on novelty of the work and targets achieved to what extent.

When considering where to take your project, please bear in mind the time available. It is preferable to do fewer things well than to try many and not get conclusive results on any of them. However, sometimes it is useful to have a couple of strands of investigation in parallel to work on in case delays occur.

Additional scope or challenge if taken as a Year-4 project: The project can be extended in many ways based on time availability. If student wants to extend the project toward Y4, the work should include the simulation modelling of human body/phantom (that includes skin and muscle) to characterise the antenna performance. Based on this modelling, the antenna design can be optimised for practical use in biomedical applications and the work can lead to a paper publication.

Please speak to Syeda Fizzah Jilani (sfj7) if you consider doing this project.

Novelty, degree of difficulty and amount of assistance required

The project will provide knowledge of the significance of the electromagnetic spectrum especially THz range, role of THz antenna and its utilisation in practical applications. The student will gain expertise in using an antenna design software and will successfully design a THz antenna for potential use in biomedical applications. At the end of the project, the student will provide a technical report based on the theoretical and simulation analysis. However, depending on the novelty and potential of the work, a brief conference publication can be planned.
