Coexistence of surface lattice resonances and bound states in the continuum in a plasmonic lattice

Trinh, Quoc Trung; Nguyen, Sy Khiem; Nguyen, Dinh Hai; Tran, Gia Khanh; Le, Viet Hoang; Nguyen, Hai-Son; Le-Van, Quynh (2022-03-14)

We present a numerical study on a 2D array of plasmonic structures covered by a subwavelength film. We explain the origin of surface lattice resonances (SLRs) using the coupled dipole approximation and show that the ...
Engineering a light–matter strong coupling regime in perovskite-based plasmonic metasurface: quasi-bound state in the continuum and exceptional points

Lu, Leran; Le, Van Quynh; Ferrier, Lydie; Drouard, Emmanuel; Seassal, Christian; Nguyen, Hai Son (2020-11-12)

We present theoretically the formation of exciton–photon polaritons and exciton-surface plasmon polaritons in a perovskite-based subwavelength lattice on the metallic plane. It is shown that the latter polaritons will be ...
Ultra‐broadband and fexible metamaterial absorber based on MoS2 cuboids with Mie resonances

Duong, Thi Ha; Man, Hoai Nam; Bui, Son Tung; Bui, Xuan Khuyen; Vu, Dinh Lam; Le‐Van, Quynh (2023-03-02)

In this work, we present a type of flexible and broadband metamaterial absorber operating in the GHz range. The proposed structure consists of three layers: a periodic square-shaped array made of molybdenum disulfide (MoS2) ...
