Near-Field Mechanical Fingerprints for THz Sensing of 'Hidden' Nanoparticles in Complex Media
Ricardo Martin Abraham-Ekeroth, Dani Torrent
Terahertz (THz) spectroscopy holds transformative potential for non-invasive sensing, yet characterizing individual nanoparticles in complex biological environments remains challen…

Control and sorting of eccentric all-dielectric core-shell nanoparticles using two counter-propagating plane waves
Ricardo Martin Abraham-Ekeroth, Marcelo Fabian Lester
Many typical nanoscale structures consist of dielectric nanoparticles with an inevitable oxide-generated coating around them. Depending on the fabrication techniques, these coating…

Radioplasmonics: design of plasmonic milli-particles in air and absorbing media for antenna communication and human-body in-vivo applications
Ricardo Martin Abraham-Ekeroth
Surface plasmons with MHz-GHz energies are predicted by using milliparticles made of metamaterials that behave like metals in the radiofrequency range. In this work, the so-called…
