We present a density-based topology optimization scheme for locally optimizing the electric power dissipation in nanostructures made of lossy dispersive materials. By using the complex-conjugate pole-residue (CCPR) model, we can accurately model any

Transient absorption in plasmonic materials has recently attracted attention of the chemistry and optics communities as a technique to understand dynamic processes and hot carriers generation on ultrafast timescales. In this context, hybrid Au/CuS na

Dielectric metasurfaces can show multi-resonant response with high Q-factors in the visible range due to multipole coupling. This work suggests that these collective resonances in all-dielectric metasurfaces can be modified if adjacent to an anisotro

COVID-19 is an infectious disease that can progress from carrier and mild symptoms of acute respiratory infections to bilateral pneumonia, severe respiratory failure, acute respiratory distress syndrome (ARDS), multiorgan failure, sepsis and shock. O

In the last decades nanostructures have unlocked myriads of functionalities in nanophotonics by engineering light-matter interaction beyond what is possible with conventional bulk optics. The space of parameters available for design is practically un

Dynamic control of metamaterials and metasurfaces is crucial for many photonic technologies, such as flat lenses, displays, augmented reality devices, and beam steering, to name a few. The dynamic response is typically achieved by controlling the pha

Anapole states are broadly investigated in nanophotonics for their ability to provide field enhancement and transparency. While low extinction has been achieved in dielectric nanoparticles due to the absence of intrinsic losses, in the case of plasmo

Topology optimization techniques have been applied in integrated optics and nanophotonics for the inverse design of devices with shapes that cannot be conceived by human intuition. At optical frequencies, these techniques have only been utilized to o
