Nanoplasmonic concurrent dual band antennas using metal‐insulator‐metal step impedance resonators

Abstract

Nanoplasmonic antennas are the one of the major elements in the recognition of upcoming nanoscale wireless communication systems. In this paper, the design and analysis of two multiband antennas operating at optical bands O and L bands, using metal-insulator-metal (MIM) slot waveguide based step impedance resonators (SIRs) and coplanar waveguide (CPW) fed line has been investigated. The simulation results of the two antennas (A) and (B) are obtained by using full wave simulation software (CST Microwave Studio Suite) with the return loss −20 dB and −30.79 dB at desired optical bands. The antenna (A) has a gain of 8 dBi and 7.48 dBi at 1275 nm and 1616 nm wavelengths, similarly antenna (B) has a gain of 8.46 dBi and 6.23 dBi at 1294 nm and 1613 nm wavelengths. The radiation pattern of the simulated results shows the omnidirectional pattern at desired wavelengths, which is very useful for nanoscale wireless communication systems.

Design and analysis of dual‐band plasmonic band pass filter using meandering step impedance resonator

“…SPPs can be utilized to control light at the nanoscale, enabling the development of nanophotonic devices such as waveguides, 1 optical interconnects, 2 multiplexers, 3 and nanoantennas. 4 SPPs can be used to enhance light and matter interaction, making them useful for applications like surface-enhanced fluorescence spectroscopy and surface-enhanced raman spectroscopy. In recent years, plasmonic has been presented as a future technology in photonic integrated circuits.…”

“…The designed MSIR has demonstrated a good passband response at wavelengths λ = 1414-nm (E-band) and 1577-nm (L-band) as well as turnability with design parameters. This filter achieved a large frequency spectral range of 139 nm and a high Q factor of ~3 × 10 4 . This work enhances the capability of on-chip filtering in the plasmonic platform.…”

“…In comparison to other piezoelectric materials, LN has a low intrinsic materials loss, a low-temperature coefficient of frequency (TCF), stable electromechanical responses, CMOS (Complementary Metal-Oxide Semiconductor) compatibility, moderate phase velocity but with low dispersion, low RF losses, GHz capability, and, most importantly, a high intrinsic electromechanical coupling coefficient, making it an excellent candidate for piezoelectric applications [4][5][6]. Nanoscale wireless communications can also be recognized defining nano-plasmonic antennas on this material system on insulator platform [7].…”

“…Due to this feature, SPPs are used in highly integrated optical circuits as information carriers. Recently, several optical devices, such as antennas [7], nanowires [8], disc resonators [9], tapered grooves [10], bends, splitters [11] and filters [12], have been investigated experimentally or theoretically. In recent years, SPPs has shown potential in many different applications, such as manipulating and guiding the light on deep subwavelength scales [13,14].…”
