PGR Rachel Lennon appointed as Postgraduate Research Rep for CDT Metamaterials for Student Guild

Our CDT in Metamaterials 2nd year PGR Rachel Lennon has recently been appointed to the Student Guild post of Postgraduate Research Rep for CDT Metamaterials.

Congratulations to Rachel, and well done for stepping up to take on this role.

She will act as academic representative for the CDT and her job is to represent the interests of the CDT PGR community to the Guild, University and Doctoral College: (

This is a new role that was up for election through the Guild, and will be incorporated as part of the CDT Student Advisory Group (SAG).

We have yet to establish the communication structures between Rachel and her ~60 peers within the CDT, to support the aim of developing a 2-way communication structure, where Rachel is able to represent all cohorts appropriately within the wider University landscape and can feed back any Guild information to the CDT PGRs.


We aim to host role introduction meetings with Rachel, SAG, and the cohorts soon.

New Publication: ‘Microwave Superdirectivity with Dimers of Helical Elements’

Congratulations to third year PGR Pavel Petrov, whose article ‘Microwave Superdirectivity with Dimers of Helical Elements’ was published yesterday in Physical Review Applied.

Pavel summarises his article:

This paper demonstrates experimental realisation of the subwavelength superdirective antenna that reaches close to theoretical maximum of directivity without using complex feeding network. We introduce a novel design of superdirective dimer using helical elements, and describe how parameters of such structures can be optimised using our analytical method. We than show how the geometric parameters of helices and the conductivity of material used may affect directivity, efficiency and gain of the optimised dimer structure. This work is a result of the year and a half of hard work which has been sponsored by DSTL and is a part of SYMETA collaboration.
