We simulated the remagnetization dynamics of the ultra-dense and ultra-thin magnetic dot array system with dipole-dipole and exchange coupling interactions. Within the proposed 2D XY superlattice model, the square dots are modeled by the spatially modulated exchange-couplings. The dipole-dipole interactions were approximated by the hierarchical sums and dynamics was reduced to damping term of t...

A large square array of thin dipoles has a well-behaved scan resistance over a wide bandwidth. Such an array requires reactance matching with frequency, but not with scan angles. The scan element pattern (SEP) shows only small changes over a 5 : 1 bandwidth. However, a dipole/screen array is suitable for wide-band scan only in the H-plane.

The detection of a dipole anisotropy in the sky distribution of sources in large-scale radio surveys can be used to constrain the magnitude and direction of our local motion with respect to an isotropically distributed extragalactic radio source population. Such a population is predicted to be present at cosmological redshifts in an isotropically expanding universe. The extragalactic radio sour...

We present a probe factor for a simple measurement device, which can be used to determine in-situ electrical resistivity in soils or other penetrable bodies. The probe is primarily sensitive to the material immediately surrounding it and therefore is ideal for determining localized conductivities. The geometry of the probe can be scaled to effectively adjust the region of interest. The calibrat...

The stability of dynamic dipole-dipole interactions in a quantum dot array is estimated, and a novel solid state quantum CCN (controlled controlled not) gate having a block structure of quantum dot array is proposed. Quantum mechanical coherence is expected to be maintained, and both the bit error and the phase error are reduced by the ensemble effects in the block. The overall process of quant...

Abstract-In this paper, a single neuron neural network beamformer is proposed. A perceptron model is designed to optimize the weights of a dipole array antenna to steer the beam to desired directions. The objective is to reduce the complexity by using a single neuron neural network and utilize it for adaptive beamforming in dipole array antennas. The optimized coefficients calculated from the s...
