This paper discusses an elliptical ultrawideband (UWB) antenna and a dual-band UWB notch antenna. To achieve bandwidth, two corner cuts are etched into the rectangular slot on partial ground plane. An inverted-U-shaped conductor-shaped resonator utilized to characteristics The suggested has overall dimension of 24×32 mm2. gain 4.9 dB, bandwidth 2.5–11 GHz, linear phase response, group delay les...
In this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. The shape of ring resonator filter adding and dropping that wehave proposed is Race Track. This filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. Transmissionefficien...
Coherent beam combining of many fiber lasers by the Y-shaped complex resonator method realizes both power scaling and spectral narrowing. The basic characteristics of this Y-shaped coherent array, scalability of power summation, and bandwidth narrowing property are presented. As high as 85% addition efficiency with only a few longitudinal-modes was obtained in an array of eight 10-nm bandwidth ...
We report the experimental realization of deformed microcavity quantum cascade lasers (QCLs) with a Limaçon-shaped chaotic resonator. Directional light emission with a beam divergence of θ‖ ≈ 33 from QCLs emitting at λ≈ 10μm was obtained in the plane of the cavity for deformations in the range 0.37< ε < 0.43. An excellent agreement between measured and calculated far-field profiles was found. B...
A novel CPW-fed antenna capable of triple-band operation for WLAN/WiMAX applications is presented and investigated in this paper. The proposed antenna simply consists of three elements viz. folded open stub, L-shaped open stub, and Y-shaped resonator. By using the three elements, triple-band antenna operating at 2.5/3.5/5.5 GHz can be achieved. The antenna impedance bandwidths for |S11| ≤ −10 d...
In this research paper, the sensing capabilities of a tri circle split ring resonator shaped metamaterial is shown within X-band frequency range for detection various oil samples both theoretically and experimentally. Mathematical modelling was used to analyze sensor efficiency samples. A new sample holder has been made proposed structure, it showed significant performance. The simulated measur...
