A case of three-conductor lines is analyzed. The currents in multiconductor transmission lines (MTL) are solved from MTL equation; then, electric dipole sequences and mirror methods are used to estimate the total radiated emissions (RE) induced by these currents. The simulations show that RE of MTL is nonlinear to the one of single circuit. The electric field intensity of MTL is about 1~3 dB smaller...
A numerical method is presented in this paper to determine the transient electric field inside wind turbine towers struck by lightning. The tower is modelled by a coupled RLC network and the lightning transient responses of the network are calculated by solving its equivalent calculation circuit. The formula of transient electric field is derived from Maxwellpsilas equations based on the obtained...
Complex permittivity of the conductor-dielectric compound was calculated based on the effective medium theory. Four main results are as follows: microwave absorbing peak shows a blue shift with the increase of conductivity of the inclusion; Increasing the permittivity of the dielectric embedding matrix, significant amplification of the effective permittivity is observed; For fixed surface fraction,...
This paper presents a novel adaptive method for drawing 2-D electric lines of force of electrostatic field. The proposed method is based on high order Taylor expansion technique. By adaptively controlling the drawing step length, the proposed method can meet high drawing precision requirement. The principle, implementation and prerequisites of the proposed method are discussed. Numerical examples...
When electric field is measured, one kind of optical fiber measurement system is often used. And we are often concerned with the effect of the device on electromagnetic wave distribution. in this paper, the finite-difference time-domain (FDTD) method is used to model the effect of optical transmitter on EMP (electromagnetic pulse) plane wave distribution. From the numerical result, we find the law...
At present there are several methods to do EMI measurements in GTEM cell, such as EDM, MDM, Linear, Wilsonpsilas method and so on. But the difference between the calculated results of these methods and the EMI results measured in OATS (open area test site) is very large in some situation. This article provides a new method to calculate electric field intensity in GTEM cell using the equivalent dipole...
An equivalent model of magnetic dipole for shielding efficiency (SE) estimation of shielding cavity with slots is presented. SE estimation of cavity is based on the coupling theory of slot and its equivalent model of magnetic dipole. The solution of electric field and the distributing regularity of SE in the cavity can be obtained by the model. The validity is given by the well matched result of the...
