“…We, therefore, employ Δρ = Δz = 1 nm and Δφ = 15 • after checking the results in the BOR-FDTD method. More importantly, recent works reveal that there exist limitations of Drude-Lorentz model in the case where metallic objects are arranged in close proximity to each other, i.e., so-called nonlocal effects [17], [18]. Inclusion of the nonlocal effects is yet to be researched.…”

A plasmonic black pole (PBP) consisting of a series of touching spherical metal surfaces is analyzed using the finite-difference time-domain (FDTD) method with the periodic boundary condition. First, the wavelength characteristics of the PBP are studied under the assumption that the PBP is omnidirectionally illuminated. It is found that partial truncation of each metal sphere reduces the reflectivity over a wide wavelength range. Next, we consider the case where the PBP is illuminated with a cylindrical wave from a specific direction. It is shown that an absorptivity of more than 80% is obtained over a wavelength range of λ = 500 nm to 1000 nm. Calculation regarding the Poynting vector distribution also shows that the incident wave is bent and absorbed towards the center axis of the PBP.

A metallic nanocylinder array was previously proposed for the propagation of localized light generated in nanosized objects. However, the plasmon resonant wavelength for each cylinder shifts significantly with the propagation of light. In this study, a metallic nanoelliptic cylinder waveguide is investigated to control the plasmon resonant wavelength shift. The finite-difference frequency-domain (FDFD) electromagnetic solver is used to reduce the computational time. The relationship between the cross-section of the cylinder and the plasmon resonance for the metal is described with the hydrodynamic Drude model. The effectiveness of the proposed waveguide in controlling the resonant wavelength shifts is confirmed by examining the plasmon propagation for 30 nanocylinders.
