One solution is to rotate a circular array antenna so as to decrease the speed of receiving antenna relative to the ground [1]. When the vehicle speed changes, the rotating antenna needs to keep the optimum rotation speed. To solve this problem, we proposed a control method of the rotating...
In this work, a two-layer Rotman lens-fed antenna array is introduced to generate five-mode OAM radio beams. Through the integrated implementation of the multilayer lens-fed antenna array, a viable solution is obtained for the generation of multi-mode OAM radio beams. The lens-fed array has...
Glioblastoma (GBM) is a highly aggressive primary brain tumour and is resistant to nearly all available treatments, including natural killer (NK) cell immunotherapy. However, the factors mediating NK cell evasion in GBM remain largely unclear. Here, we r
If the rotation angles around the x, y, and z coordinate axes of the frame of reference attached to the cone are denoted as ϕ, θ, ψ, respectively, then the rotation matrix used is Table 8.1. Algorithm for the Computation of Grain Interactions With the Cone 1 The positions of the ...
The variations of the grey level values aside the center circle are modeled as an exponential function of the distance to the center circle. We expect that the exponential distribution, for instance a Gaussian distribution, of the gray level values, facilitates the transfer of array processing meth...
specifically using hexagonal star array (HSA) geometry. The approach provides a unique self-interference cancellation (SIC) capability across multiple bands (MB-SIC), achieved through translation or rotational transformations of self-similar or self-affine array structures. Simulation results demonstrate si...
$$\begin{array}{c}{{\mathrm{N}}\;{\mathrm{fixation}}}\left({\mathrm{kg}}\;/{\mathrm{ha}}^{-1}\right)={\mathrm{Ndfa}}/100\times {\mathrm{Y}}/{\mathrm{NHI}}\end{array}$$ where Ndfa is the percentage of N uptake derived from biological N fixation, Y is the harvested yiel...
All array apertures have an angle β = 45° between each element. E-Field and Phase planes in the simulation results are observed from a distance of 300 mm away from each array to ensure the observation plane captures the full E-Field rotation and Phase profile away from the null ...
