We reveal that metasurfaces created by seemingly different lattices of (dielectric or metallic) meta-atoms with broken in-plane symmetry can support sharp high-Q resonances arising from a distortion of symmetry-protected bound states in the continuum. We develop a rigorous theory of such asymmetric periodic structures and demonstrate a link between the bound states in the continuum and Fano resonances. Our results suggest the way for smart engineering of resonances in metasurfaces for many applications in nanophotonics and metaoptics.

We investigate the problem of N identical bosons that are coupled to an impurity particle with infinite mass. For noninteracting bosons, we show that a dynamical impurity-boson interaction, mediated b...
Metasurfaces provide new and promising mechanisms to control and manipulate light at the nanoscale. While most metasurfaces are designed to operate in the linear regime, it was recently shown that suc...
Nonlinear holographic metasurfaces have been intensively studied due to their potentials in practical applications. So far, nonlinear holographic metasurfaces have only been realized with plasmonic na...
Mie-resonant high-index dielectric nanoparticles and metasurfaces have been suggested as a viable platform for enhancing both electric and magnetic dipole transitions of fluorescent emitters. While th...
We investigate optical second-harmonic generation (SHG) from metasurfaces where noncentrosymmetric V-shaped gold nanoparticles are ordered into regular array configurations. In contrast to expectation...
Pancreatic cancer progresses rapidly and has a higher death rate. Albumin-bound paclitaxel is a new generation of paclitaxel . Albumin-bound paclitaxel is recommended as a class 1A evidenc...
High-efficiency post-dilution online hemodiafiltration (OL-HDF) using high-flux dialyzer and requiring high blood flow rate (BF ≥400 mL/min) has been reported to enhance protein-bound to...
Weekly Nanoparticle Albumin-Bound Paclitaxel (Abraxane) + Weekly Cetuximab + Radiation Therapy (IMRT, Intensity-Modulated Radiation Therapy) in Patients With Stage III-IVB Head and Neck Squamous Cell Carcinoma (HNSCC)
For patients with this type of cancer, one standard treatment option is cetuximab (Erbitux®) + radiation. We wish to study the addition of albumin-bound paclitaxel (Abraxane®) to this st...
The purpose of this study is to see if a treatment regimen with a combination of paclitaxel protein bound (also known as nab-paclitaxel), gemcitabine, and cisplatin when given with high do...
Homocysteine (Hcy) and asymmetric dimethylarginine (ADMA) have recently been recognized as potential risk factors for atherosclerosis in the general population, and the metabolism of each ...
