“…To clarify the basic principle of the proposed configuration, we can use the Transmission Line Method (TLM) [36]. Each stub has its own characteristic impedance of 𝑍 0 which can be calculated by using a surface integral to determine the power 𝑃 carried by the waveguide and a loop integral to calculate the current flow 𝐼 [37].…”

In this paper, a plasmonic power splitter and a Wavelength Division Multiplexer (WDM) based on metal-insulator-metal (MIM) surface are investigated. By using Finite Difference Time Domain (FDTD) method, the transmission spectra of the suggested devices are extracted. The simulation results demonstrate that the equal transmitted wavelengths of the two output ports can be easily tuned by changing the geometric parameters of the structure. Then, the structure geometries are modified into a WDM. Subsequently, the dependence of demultiplexing wavelengths on geometrical parameters of the structure is investigated. Besides being highly compact and efficient, having narrow-band spectra and low reflectance coefficient are the other main advantages of these devices. Therefore, the power splitter and wavelength division multiplexer presented can be of great interest in a wide range of applications from highly integrated photonic circuits to optical communication systems.

A T-stub Square Ring Resonator (SRR) based Ultra-Wide Band (UWB) Band Pass Filter (BPF) is studied and investigated in this paper. The proposed filter is based on coupled feed line connected to the T-stub SRR. Ultra-wideband characteristics can be realized by adjusting the T-stub lengths and coupling the gaps between both sides of waveguides and SRR. The characteristics of the T-stub SRR show that the miniaturized UWB BPF can be operated at THz frequencies. The proposed UWB filter is simulated and analyzed using the Finite Differential Time Domain (FDTD) solver-based Computer Simulation Technology (CST) studio suite. The resonance conditions are explained and the transmission performance of the filter agrees with the simulated and theoretical calculations. The proposed filter is best suitable for Electronic-Plasmonic Integrated Circuits (EPICs).

“…Metamaterials have emerged as a new concept of science, material science, engineering, physics, optics and plasmonics 1 . The surface plasmon polariton (SPP) 2‐7 has attracted increasing attention in the past decade. There is also an increased concern in extending the exclusive properties of the SPP to lower frequencies for the investigation of various devices and integrated circuits in the microwave regimes and terahertz (THz) 8‐24 .…”

Recently, Plasmonics and metamaterials have been receiving consideration. Spoof surface plasmon polaritons (SSPPs) are a type of electromagnetic surface wave that to a certain limit shares an analogous behavior with surface plasmon polariton (SPP) at microwave frequency domain. The significant point is that the dispersion relation of SSPP is principally controlled by the geometry of the pattern using plasmonic metamaterial. The motivation behind this work is to explore and implement the subwavelength propagation or nanoconfinement of wave beyond the diffraction limit using plasmonic metamaterial‐inspired SSPP structure in the microwave frequency domain. In this article, the conventional symmetric H‐shaped unit cell is modified into a new unit cell. Using this modified unit cell, a new SSPP structure is designed which provides broadband bandpass filter (BPF) characteristics. The measurement shows the passband of BPF is 1.2 to 6.0 GHz with insertion loss less than 2 dB. The size of the fabricated SSPP BPF is 26 × 4 cm.
