In this work, an ultra-wideband (UWB) optical bandpass filter (BPF) based on nanoplasmonic structure is designed and thoroughly analyzed. The proposed BPF encompasses asymmetric metal-insulator-metal (MIM) slot waveguide that incorporates a gap-coupled series parallel square ring resonators (SRRs). characteristic parameters of the MIM are analyzed with full-wave analysis conformal mapping techn...

Herein, two simple configurations of Fano resonance-based plasmonic sensors are proposed for temperature and biosensing applications. The device optimization sensing performance numerically investigated via two-dimensional finite element method (2D-FEM). former configuration is quite based on the side-coupled circular cavity (SCCC), whereas in latter, encapsulated ring separated by a small gap ...

In this research, we will seek to design and numerically evaluate a refractive index nano-sensor based on the resonant system with metal insulating waveguide (MIM) that forms wide range of wavelengths. To proposed sensor structure, use two cavities rings different dimensions plasmonic waveguides. After designing examine wavelengths resonators by finite difference method time domain, because dir...

Novel gemini supra-amphiphiles, [Mim-4-Mim][DBS](2) and [Mim-4-Mim][DS](2), were facilely constructed. A slight variation of building blocks can effectively modulate the driving forces for the fabrication of gemini supra-amphiphiles, thus leading to the fine control of subsequent self-assemblies. [Mim-4-Mim][DS](2), constructed via electrostatic attraction, tends to form micelles and hexagonal ...
