Plasmonic quarter-wave plate with U-shaped nanopatches

None sharp corner localized surface plasmons resonance based ultrathin metasurface single layer quarter wave plate

“…The transmission of their proposed quarter wave plate is 46% at the wavelength of 1550 nm. A plasmonic quarter-wave plate based on 60 nm thick U-shaped Ag nanopatches array in the near-infrared range is designed and presented by Chen et al 15 . Strong LSP resonances are excited around different sharp corners of the U-shaped silver nanopatches according to the polarization of the incident light, leading to the different phase delays between x- and y-polarized components.…”

“…The phase difference of π/2 and amplitude ratio of 1 is realized simultaneously at the wavelength of 834 nm with the transmission of 0.46. This proposed NCQW suggests a new way of exciting LSP resonances and designing wave plates, which has huge application prospects in advanced nanophotonic devices and integrated photonic systems 3 , 15 , 18 – 20 .…”

Non-corner Localized Surface Plasmons Resonance Based Ultrathin Metasurface Single-layer Quarter Wave Plate

“…Traditional wave plates are mostly manufactured by bulky birefringent crystals, which suffer from depth of phase modulation and di culties in integration. Recently, as the very fast development of metasurface structures, localized surface plasmons (LSP) resonance based wave plates have been widely researched and published [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] . Zhao et al proposed plasmonic metasurfaces formed by orthogonal elongated nanorods and complementary nanoslits 3 .…”

Developer Design of Hybrid Plasmonic Nano Patch Antenna with Metal Insulator Metal Multilayer Construction

“…e topic of optical antennas has a historic background in previous years, but it has recently attached renewed interest for different reasons. One of the reasons is the availability of various routine nanoscale fabrication technologies that allow suitable sized structures to be made and explored as a way of harnessing nanoantennas [1][2][3][4][5][6][7][8][9][10]. A variety of nanoantennas have been investigated for different applications from light excitation or emission [11] to photovoltaics [12], scatters to redirect incident light [13], and optical wireless nanolink [14].…”
