Scattering Cancellation based Cloaking for the Maxwell-Cattaneo Heat Waves
M. Farhat, S. Guenneau, P. -Y. Chen +2
In this work we theoretically propose scattering cancellation-based cloaks for heat waves that obey the Maxwell-Cattaneo equation. The proposed cloaks possess carefully tailored di…
Generalized Parity-Time Symmetry Condition for Enhanced Sensor Telemetry
Pai-Yen Chen, Maryam Sakhdari, Mehdi Hajizadegan +4
Wireless sensors based on micro-machined tunable resonators are important in a variety of applications, ranging from medical diagnosis to industrial and environmental monitoring.Th…
Spatially Separated Self-Assembled Silver Dendrites for Highly Sensitive SERS Applications
D. V. Yakimchuk, E. Yu. Kaniukov, S. I. Lepeshov +11
Even after more than four decades of rapid-pace advances, the adoption of Surface-Enhanced Raman Scattering (SERS) remains limited, due to the difficulties in fabrication of effect…
Angular-Momentum Selectivity and Asymmetry in Highly Confined Wave Propagation Along Sheath-Helical Metasurface Tubes
Yarden Mazor, Andrea Alù
Highly confined surface waves present unique opportunities to enhance light interactions with localized emitters or molecules. Hyperbolic dispersion in metasurfaces allows us to ta…
Enhanced Excitation and Emission from 2D Transition Metal Dichalcogenides with All-Dielectric Nanoantennas
Sergey Lepeshov, Alex Krasnok, Andrea Alu
The recently emerged concept of all-dielectric nanophotonics based on optical Mie resonances in high-index dielectric nanoparticles has proven a promising pathway to boost light-ma…
Non-Reciprocal Hyperbolic Propagation over Moving Metasurfaces
Yarden Mazor, Andrea Alù
Hyperbolic propagation offers exciting opportunities in nanophotonics, from sub-diffraction imaging to enhanced local density of states. This transport regime is typically induced…
Nanophotonic engineering of far-field thermal emitters
Denis G. Baranov, Yuzhe Xiao, Igor A. Nechepurenko +3
Thermal emission is a ubiquitous and fundamental process by which all objects at non-zero temperatures radiate electromagnetic energy. This process is often presented to be incoher…
Valley-Selective Response of Nanoantennas Coupled to 2D Transition Metal Dichalcogenides
Alex Krasnok, Andrea Alu
Monolayer (1L) transition metal dichalcogenides (TMDCs) are attractive materials for several optoelectronic applications because of their strong excitonic resonances and valley-sel…
What is Nonreciprocity?
Christophe Caloz, Andrea Alù, Sergei Tretyakov +3
This paper aims at providing a global perspective on electromagnetic nonreciprocity and clarifying confusions that arose in the recent developments of the field. It provides a gene…
Nonreciprocal Cavities and the Time-Bandwidth Limit
Sander A. Mann, Dimitrios L. Sounas, Andrea Alù
The time-bandwidth limit inherently relates the lifetime of a resonance and its spectral bandwidth, with direct implications on the maximum storage time of a pulse versus its frequ…
What is Nonreciprocity? Part II
Christophe Caloz, Andrea Alù, Sergei Tretyakov +3
This paper is the second part of a two-part paper on \emph{Electromagnetic (EM) Nonreciprocity (NR)}. Part~I has defined NR, pointed out that linear NR is a stronger form of NR tha…
Embedded Scattering Eigenstates Using Resonant Metasurfaces
Alex Krasnok, Andrea Alu
Optical embedded eigenstates are localized modes of an open structure that are compatible to radiation yet they have infinite lifetime and diverging quality factors. Their realizat…
