In this study, a new refractive index sensor based on a metal-insulator-metal waveguide coupled with a notched ring resonator and stub is designed. The finite element method is used to study the propagation characteristics of the sensor. According to the calculation results, the transmission spectrum exhibits a typical Fano resonance shape. The phenomenon of Fano resonance is caused by the coup...

A compact rectangular printed antenna with dual band-notches is proposed for ultra-wideband (UWB) applications. The dual band-notch characteristics have been realized by etching one C-shaped parasitic element and rectangular split ring resonator above the ground plane. The proposed antenna can achieves a wide bandwidth from 2.9-11 GHz with the dual notched bands centred at 5.25 GHz and 5.8 GHz....

Notched tensile bars of a high strength structural steel were loaded to void coalescense. The resuIts show that the damage curve determined using radially loaded specimens is not valid for specimens under nonradial loading. The results of the experiments with different load histories of notched tensile bars show, that a single parameter criterion like a damage parameter is not sufficient to des...

In this paper, a compact ultra wideband (UWB) monopole antenna with a band-notched characteristic is presented. The bandnotched characteristic is achieved by inserting a U-shaped slot in the half elliptical ring radiating patch. The measured bandwidth of the designed antenna for |S11| 6 −10 dB spans 3.1 GHz to 9.3 GHz with a notched band (|S11| > −10 dB) spanning 5.12GHz to 5.99 GHz. A quasi-om...

UWB antenna with dual notched characteristics fed by microstrip transmission line is presented in this paper. The tapered connection between the rectangular patch and the feed line is used to produce a good impedance matching from 2.3 to 11.5 GHz. A dual band frequency notches are achieved using UDGS loaded with lumped capacitors. The first notch frequency band is achieved using DGS to reduce t...

In a previous study, search for a notched-disk target abutting a square among complete-disk nontargets and squares was inefficient in 250-ms exposures, but relatively efficient in 100-ms exposures. This finding was interpreted as evidence that amodal completion proceeds through a mosaic and then a completion stage, with the latter preempting the former. We used the same target but changed its c...

A compact ultrawideband (UWB) monopole antenna with two U-shaped slots for WLAN and WiMAX dual band-notched functions is proposed and experimentally studied. The proposed antenna with the size of 28mm × 24mm × 1.6mm is excited by a 50Ω microstrip feed line. The band-notch functions are realized by loading two approximate half-wavelength U-shaped slots which change the current distribution on th...

The present paper investigates the importance and relevance of using microstructural length scale parameters in estimating the high-cycle fatigue strength of notched plain concrete. In particular, the accuracy and reliability of the Theory of Critical Distances and Gradient Elasticity are checked against a number of experimental results generated by testing, under cyclic bending, square section...
