چکیده مقاله
The concentration of optical energy at a specific point has gained significant importance and wide applicability in nanoimaging and nanosensing technologies This is particularly notable in the ultraviolet wavelength region 300–400 nm , which offers high spatial resolution, stronger interaction with matter, enhanced sensor sensitivity, and high‑density optical data storage Despite the substantial potential of this spectral range, several limitations still exist In this article, a trapezoidal plasmonic silver nanotip is investigated for the concentration of the electric field within the 300–400 nm wavelength range Silver is selected due to its favorable balance between the interband transition threshold and intrinsic losses To optimize the geometrical dimensions, a multiparametric sweep over the nanotip dimensions small base and large base is performed, and the optimal configuration is subsequently identified
