@article{10902/28887, year = {2019}, month = {10}, url = {https://hdl.handle.net/10902/28887}, abstract = {A single-layer, all-dielectric metasurface exhibiting a strong toroidal resonance in the low-atmospheric loss radio window of the subterahertz W-band is theoretically proposed and experimentally demonstrated. The metasurface is fabricated on a high-resistivity floating-zone silicon wafer by means of a single-process, wet anisotropic etching technique. The properties of the toroidal mode of both the constituent dielectric elements and the metasurface are rigorously investigated by means of the multipole decomposition technique and full-wave simulations. The experimental demonstration of such a compact, all-silicon metasurface opens new venues of research in the investigation of toroidal modes and the engineering of functional millimeter-wave components, which can be scaled to terahertz and higher frequencies of the electromagnetic spectrum.}, organization = {This work was supported by the European Union COST Action CA16220 “European Network for High Performance Integrated Microwave Photonics,” by the Comunidad de Madrid and FEDER Program under grant S2018/NMT-4326, the Ministerio de Economía y Competitividad of Spain (TEC2013-47342-C2-2-R), and the mobility programs of Carlos III University and “José Castillejo” of the Ministerio de Educación, Cultura y Deporte of Spain.}, publisher = {John Wiley and Sons Inc.}, publisher = {Advanced Optical Materials, 2019, 7(19), 1900777}, title = {All-dielectric silicon metasurface with strong subterahertz toroidal dipole resonance}, author = {Zografopoulos, Dimitrios C. and Ferraro, Antonio and Algorri Genaro, José Francisco and Martín Mateos, Pedro and García Cámara, Braulio and Moreno Oyervides, Aldo and Krozer, Viktor and Acedo Gallardo, Pablo and Vergaz Benito, Ricardo and Sánchez Pena, José Manuel and Beccherelli, Romeo}, }
