@article { , title = {An Optically-Programmable Absorbing Metasurface}, abstract = {A tunable metasurface absorber is presented in this work using an optically-programmable capacitor as the tuning element. The tuning element does not employ conventional semiconductor technologies to operate but rather a bases its tuning by changing the optomechanical properties of its dielectric, poly disperse red 1 acrylate (PDR1A). Doing so there are no conventional semiconductor devices in the RF signal path. The metasurface operates at a design frequency of 5.5 GHz and it achieves an optically-tuned bandwidth of 150 MHz, from 5.50 GHz to 5.65 GHz.}, conference = {2018 IEEE International Symposium on Circuits and Systems (ISCAS)}, doi = {10.1109/ISCAS.2018.8351874}, isbn = {9781538648810}, issn = {0271-4310}, organization = {Florence}, publicationstatus = {Published}, publisher = {Institute of Electrical and Electronics Engineers}, url = {https://hull-repository.worktribe.com/output/833737}, volume = {2018-May}, keyword = {Specialist Research - Other}, year = {2018}, author = {Kossifos, K.
