چکیده

The back-scattering from front edge diffraction contributes significantly to mono-static radar cross section under TE-polarization when the specular reflection of an object is eliminated by elaborate shaping. With aim suppress thin metallic edge, we propose achieve wideband (RCS) reduction integrating absorbing structure (AS) in edge. unit cell AS composed a longitudinal array strips with linearly decreasing lengths. Under TE-polarized illumination, spoof surface plasmon polariton (SSPP) can be excited high efficiency. Due deep-subwavelength property SSPP, electromagnetic waves are highly confined around AS, leading strong local field enhancement and hence absorption. In this way, suppressed RCS reduced over wide band. To verify method, designed, fabricated measured prototype. results both simulation measurement indicate that our proposal scattering, whose more than 10 dB achieves at range 8.8–17.8 GHz TE polarization. This work provides new alternative suppressing may find applications compatibility, stealth, etc.

Capacitive-coupled Series Spoof Surface Plasmon Polaritons

A novel method to realize stopband within the operating frequency of spoof surface plasmon polaritons (SPPs) is presented. The stopband is introduced by a new kind of capacitive-coupled series spoof SPPs. Two conventional H-shaped unit cells are proposed to construct a new unit cell, and every two new unit cells are separated by a gap with certain distance, which is designed to implement capaci...

Novel ultra-wideband filtering of spoof surface plasmon polaritons (SPPs) is proposed in the microwave frequency using deep subwavelength planar structures printed on thin and flexible dielectric substrate. The proposed planar SPPs waveguide is composed of two mirror-oriented metallic corrugated strips, which are further decorated with parallel-arranged slots in the main corrugated strips. This...

Wideband helicity dependent spoof surface plasmon polaritons coupling metasurface based on dispersion design

The surface plasmon polaritons (SPPs) have many potential application due to their local field enhancement and sub-wavelength characteristics. Recently, the gradient metasurface is introduced to couple the spoof SPPs in microwave frequency band. One of the most important issue which should be solved is the narrowband of spoof SPPs coupling on the gradient metasurface. Here, the metasurface is p...

Chiral surface plasmon polaritons on metallic nanowires.

Chiral surface plasmon polaritons (SPPs) can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Images of chiral SPPs on individual nanowires obtained from quantum dot fluorescence excited by the SPP evanescent field reveal the chirality predicted in our theoretical model. The handedness and s...

Broadband Frequency-Selective Spoof Surface Plasmon Polaritons on Ultrathin Metallic Structure

We propose an ultrathin metallic structure to produce frequency-selective spoof surface plasmon polaritons (SPPs) in the microwave and terahertz frequencies. Designed on a thin dielectric substrate, the ultrathin metallic structure is composed of two oppositely oriented single-side corrugated strips, which are coupled to two double-side corrugated strips. The structure is fed by a traditional c...
