Funneling and Sculpting of Optical Waves Through Non-Magnetic Metasurfaces
Nasim Mohammadi Estakhri, Nooshin M. Estakhri
Efficient concentration and transport of electromagnetic energy through electromagnetically thick structures often requires resonant phenomenon and careful design considerations. H…
Coherent Virtual Absorption in Dielectric Metasurfaces
Kaizad Rustomji, Nasim Mohammadi Estakhri, Nooshin M. Estakhri
Through temporal shaping of the excitation signal, the complex-frequency scattering zeros of a lossless structure can be accessed, enabling a storage-release mechanism referred to…
Coherent Virtual Absorption in Dielectric Slabs: A Temporal Analysis of Symmetric and Asymmetric Geometries
Kaizad Rustomji, Nasim Mohammadi Estakhri, Nooshin M. Estakhri
Coherent virtual absorption refers to time-limited storage of optical energy in lossless configurations due to excitation of a complex zero frequency through proper temporal engine…
Manipulating the Nanoscale Optical Transmission with a Meta-Transmitarray
Francesco Monticone, Nasim Mohammadi Estakhri, Andrea Alu
By applying the optical nanocircuit concepts to metasurfaces, we propose an effective route to locally control light transmission over a deeply subwavelength scale. This concept re…
The Physics of Unbounded, Broadband Absorption/Gain Efficiency in Plasmonic Nanoparticles
Nasim Mohammadi Estakhri, Andrea Alu
Anomalous resonances in properly shaped plasmonic nanostructures can in principle lead to infinite absorption/gain efficiencies over broad bandwidths. By developing a closed-form a…
