Linear elastic stresses/strains for a notched component can be easily obtained from a linear elastic FEA solution.
It is observed that as W1 decreases from 1.2 to 0.6 mm and W2 increases from 0.1 to 0.6 mm, the nonuniform width slots on the patch convert to uniform width slots and the ratio between the first and third notched band centre frequencies increases from 2 to 3.
It is observed from the plot that the bandwidth of the notched band as well as the center frequency is very sensitive to the value of [x.sub.1].
According to the figure, the range of the measurements is from 3 GHz to 10 GHz; the efficiency decreases sharply at the notched frequency band because of the resonators of the proposed antenna.
The results show that the fracture parameter of ac is greatly sensitive to the relative notch depth of notched three-point bending beam specimens, and the effective crack-length of the specimen with smaller relative notch depth is more sensitive to the relative notch depth.
The UWB BPF with triple notched bands and wide upper stopband has been designed on substrate Rogers RT/Duroid 5880 with a dielectric constant of 3.38, thickness of 0.508 mm, and loss tangent of 0.0027.
In order to create band notched behavior within ultra wide band range, two types of resonating structures are embedded in the reference UWB antenna as shown in Figure 1(b).
For comparison, Figure 3(d) shows the current distributions of the original UWB antenna without notched band at 7.5 GHz.
The proposed notched technology requires no additional circuit and exhibits design flexibility.
Second, the data are presented for each age decade in terms of the percentage of participants with unnotched audiograms and the percentage with notched audiograms.
V-notches were "double-tapped" in the same manner they would be by North Cape observers in the field (notched once, then notched in the same place again a few moments later, to remove any tissue extruding from the wound into the open space).
(9) studied the plastic deformation and slip-line fields in notched specimens of pure and rubber-toughened epoxies using the Drucker-Prager yield criterion.
