چکیده
A transmitarray adopting dual-layer polarisation rotating (PR) elements is proposed. The element comprises a pair of perpendicularly placed C-shaped slots etched on the two sides single-layer substrate and orthogonally rotates transmission wave with regard to incidence. By adjusting slot's dimension as well mirroring bottom layer element, 360° phase shift high magnitude achieved. Based proposed unit-cell, composed 529 designed developed. experimental 1-dB gain bandwidth peak aperture efficiency are 13% 44% respectively. Furthermore, sidelobe level 20 dB cross 26 obtained at 10 GHz. These promising properties demonstrate superiority for designs. In addition, this can be also good candidate folded

to the nearly constant breakthrough voltage, which yields a heat generation proportional to the tuning current. The thermal wavelength shift roughly corresponds to a temperature increase of 40K indicating a thermal resistance of -120K/W. As with the forward bias, the maximum wavelength shift is determined by the extinction of the laser operation. Under both biasing conditions the tuning behavio...
متن کاملDifferent Designs of Dual-Focus Perforated Transmitarray Antenna in Near/Far- Field Region
In this paper, the design of single-focused and dual-focused transmitarray antennas in the near-field (NF) or/and far-field (FF) applications are proposed. A unit-cell element consists of a dielectric square box with four identical holes is used. The phase compensation of the unit-cell elements depends on changing the hole radii according to the position of the unit-cell element, the feeding ho...

x y z x y xy♁z Abstract – To construct a reversible sequential circuit, reversible sequential elements are required. This work presents novel designs of reversible sequential elements such as D latch, JK latch, and T latch. Based on these reversible latches, we construct the designs of the corresponding flip-flops .Comparing with previous work, the implementation cost of our new designs, includ...
متن کاملDual-Filter Estimation for Rotating-Panel Sample Designs
Dual-filter estimators are described and tested for use in the annual estimation for national forest inventories. The dual-filter approach involves the use of a moving widow estimator in the first pass, which is used as input to Theil’s mixed estimator in the second pass. The moving window and dual-filter estimators are tested along with two other estimators in a sampling simulation of 152 simu...
متن کاملShrinkage simplex-centroid designs for a quadratic mixture model
A simplex-centroid design for q mixture components comprises of all possible subsets of the q components, present in equal proportions. The design does not contain full mixture blends except the overall centroid. In real-life situations, all mixture blends comprise of at least a minimum proportion of each component. Here, we introduce simplex-centroid designs which contain complete blend...
