“…In the traditional high-frequency method [9][10][11], we often overlook the shadow of the side effects. The impact on current of the shadow region is small; however, in some applications the scattering of their contributions can not be ignored.…”

Abstract-The improved high-frequency method for solving the bistatic scattering from electrically large conductive targets is presented in this paper. Since the previous physical optical methods overlooked the current impact of shadow zone and led to the increasing problems of the large angle bistatic calculation, the improved method is deduced by introducing the current marching technique into the conventional physical optical method. Combined with the graphicalelectromagnetic computing method that extracted the illuminated and shadow facet in accordance with the direction of the incident sort iteration, one may calculate the bistatic radar cross-section of a conductive targets object. The numerical results show that this method is efficient and accurate.

“…Monte Carlo integration technique [16] is very powerful in these circumstances, mostly for the problem involving integration, which is too difficult to solve analytically and by other available numerical methods. Efficiency of Monte Carlo integration method increases relative to other method when the dimension of the integral increases.…”

Abstract-This paper represents the force calculation in a radial passive magnetic bearing using Monte Carlo technique with general division approach (s-MC). The expression of magnetic force is obtained using magnetic surface charge density method which incurs a multidimensional integration with complicated integrand. This integration is solved using Monte Carlo technique with 1-division (1-MC) and 2-division (2-MC) approaches with a MATLAB programming. Analysis using established methods such as finite element method (FEM), semi-analytical method, and adaptive Monte Carlo (AMC) method has been carried out to support the proposed technique. Laboratory experiment has been conducted to validate the proposed method. 2-MC gives better result than 1-MC. The computation time of the proposed method is compared with the quadrature method, FEM and AMC. It is observed that the proposed method invites less computational burden than those methods as the algorithm adaptively traverses the domain for promising parts of the domain only, and all the elementary regions are not considered with equal importance.

“…The conventional MCI takes care of the singularity aspect without employing any analytical techniques such as Singularity subtraction/removal, polar co-ordinate transformation, etc. and implements the idea just by restricting the random points to fall in the singular region by including a simple statement in the program code used for the simulation purpose [7,8]. However, the proposed Halton sequence in QMCI takes care of the singularity issue automatically without even modification or inclusion of any condition in the program code and provides solution to the problem more accurately and faster than the conventional MCI with randomly generated point sequences.…”

Abstract-In this work, a Quasi Monte Carlo (QMC) IntegrationTechnique using Halton Sequence is proposed for the Electric Field Integral Equation (EFIE) in the Method of Moments (MoM) solution for scattering problems. It is found that the Halton Sequence used in QMC integration scheme is capable of handling the singularity issue in the EFIE automatically and at the same time provides solution to the scattering problems very easily. Finally the proposed technique is applied to solve the scattering problem from a finite cylinder employing the entire domain basis function expansions. The results obtained show a good agreement between the proposed and conventional technique.
