In this paper, a new sensor structure is designed, which consists of a metal-insulator-metal (MIM) waveguide and a circular protrusion and a rectangular triangular cavity (CPRTC). The characterization of nanoscale sensors is considered using an approximate numerical method (finite element method). The simulation results show that the sharp asymmetric resonance generated by the interaction between the discrete narrow-band mode and the continuous wideband mode is called Fano resonance.

Its primary structural components are a metal-insulator-metal (MIM) waveguide, a shield with three disks, and a T-shaped cavity (STDTC). The finite element approach was used to study the gadget in theory.

- The study investigates the effects of Polycarbonate (PC) and Polyvinylidene fluoride (PVDF) in creating asymmetric bilayer polymer dielectrics for electrostatic capacitors, focusing on their barrier characteristics and electrical properties based on the orientation of the applied electric fields.
- Findings indicate that while the dielectric constant of the composite remains constant regardless of the arrangement of PC and PVDF, the placement significantly affects the energy-storage capabilities.
- When PC is positioned at the negative electrode, it enhances the capacitor's performance by achieving a higher energy-storage density (5.48 J/cm) compared to other configurations and pure materials, thus demonstrating the potential of combining these polymers for better energy-storage solutions.*
Article Synopsis
- A new nanoscale refractive index transducer is proposed, utilizing a metal-insulator-metal (MIM) waveguide and a ring cavity connected to an h-shaped structure, enhancing Fano resonance effects.
- The impact of different geometric parameters on the device's performance was simulated using COMSOL software and finite element methods, revealing how these parameters influence the output Fano curves.
- The optimized design achieves high sensitivity of 2400 nm/RIU and a figure of merit of 68.57, showing promise for applications in nano-sensing and temperature detection in future integrated systems.
