“…Waveguide-based plasmonic structures utilizing surface plasmon polariton (SPP) are promising for their capability of high subwavelength scale confinement and low propagation loss [16,17], which could lead to a high-speed, miniaturized and integrated electrooptical technology. Several plasmonic waveguiding structures have been explored, such as metallic nanoparticles [18,19], metallic strips or nanowires [20,21], V-grooves [22], and slot waveguides [23].…”

Abstract-A novel surface plasmon based square-shaped ring resonator with bending metal-dielectricmetal input/output (I/O) waveguide at optical spectral range is investigated. The influence of various geometric parameters is studied in detail, with parallel finite difference time domain method. The results validate that vertical coupling disturbance can be efficiently suppressed by employing the modified I/O structure. The transmittance performance has all the resonant frequencies workable with better extinction ratios, higher finesse and higher Q-factors compared to the original plasmonic micro-ring resonator. From these analyses, it is found that the proposed waveguide is outstanding in aspects of the total field extinction and frequency selectivity characteristic.

“…The solution generated by the GA after 200 generations of evolution process is exhibited (see Figure 3), which shows the shape of the unit describing the basic periodicity cell. Considering not to yield the grating lobe [15,16] in the desired band, the optimum dimension of the unit cell is fixed at L = 660 µm. In addition, the thickness of the SiO 2 substrate is chosen at 368 µm.…”

Abstract-A satellite-borne frequency selective surface (FSS) for atmospheric sensing application is presented. This brand new type of band-pass filter has an operating frequency at 183 GHz, which is a typical frequency on H 2 O absorption line. Comprising an ultrathin gilding layer and a SiO 2 substrate layer, this complex periodic component exhibits an extremely low insertion loss (< 0.22 dB) and high isolation (> 20 dB) between closely spaced frequency channels of 45 • incident wave. Periodic Method of Moment (PMM) approach is applied to determine the initial geometrical parameters of FSS unit cell, and the optimization approach based on the Genetic Algorithm (GA) enables us to obtain the requisite spectral response and transmission characteristics for both TE and TM polarization. The experimental results show that the proposed PMM-GA technique is effective for analyzing space-borne FSS at millimeter wave range.

“…Many papers based on the Rayleigh-Sommerfeld diffraction integral or on the Fresnel diffraction integral analyze the focusing properties of inplane FZPs [7][8][9][10]. Some studies show that the deeply-etched onedimensional (1-D) gratings have many excellent properties such as high diffraction efficiency [11,12] and suppressing the sidelobes in the frequency response of a metal-insulator-metal plasmonic filter [13]. The aim of this paper is to analyze the diffraction properties of deeplyetched 2D circular Fresnel zone plates.…”

Based on the scattering theory and the Green function method, a dynamical theory is given for calculating the diffraction of deeply-etched gratings with a stratified structure substrate. The key of our method is that the patterned grating structure is considered as a perturbation to the unpatterned stratified structure rather than to vacuum. Using the first-order Born approximation and in the Fresnel diffraction region, we obtain a simple analytical expression, which can be used to calculating the scattering intensity of deeply-etched circular binary Fresnel zone plates with a stratified substrate (MDECBFZPs). The numerical results show that the focusing intensity at the foci of the MDCBFZP changes periodically with the etching depth and the thickness of the substrate film. Our results are in good agreement with FDTD simulations.
