Magnetohydrodynamic Calculation Method for Electromagnetic Sensor

Electromagnetic Vector Sensor array parameter estimation method

Joint estimation method for DOA and polarization parameters of single electromagnetic vector sensor is mostly concerned in radar signal processing now. This paper presents a new algorithm which uses the cyclostationary property of signal. It gets the estimation of DOA and polarization parameters from the noise subspace with minimum norm method. This method can reduce the estimate error of noise...

Design Analysis on Optimized Calculation Method of Wireless Sensor Network

In order to reduce node consumption and energy balance, this paper puts forward strategies for energy optimization based on improved ant colony algorithms, so that it can extend the effective time of network. This paper uses mechanism of positive feedback and negative feedback to effectively balance data traffic. In addition, it also adopts self-automatic probability transition function based o...

Quantitative measuring of pearlite in carbon steels using electromagnetic sensor

Non-destructive Eddy current (EC) technique has long been used to detect discontinuities in materials. Recently, its application has been extended to characterize materials microstructure. In order to identify different microstructures, four plain carbon steel bars with different chemical compositions (AISI 1015, 1035, 1045 and 1080) were used in annealed condition. The pearlite percentage, car...

Calculation of Lightning Electromagnetic Fields: a Review

Lightning return stroke is a self-propagating discharge with path length measured in kilometres, which extends at high speeds, sometimes approaching a significant fraction of the speed of light. Usually one is interested in the electromagnetic fields produced by lightning several tens of meters to some kilometres away. In order to calculate fields from lightning, it is modelled as a linear trav...
