An efficient open graphics library (OpenGL)-based method of moments (MoM)–shooting and bouncing ray (SBR) hybrid method is proposed in this paper to analyze the radiation pattern of an antenna above an electrically large, complicated platform. This study takes advantage of the outstanding rendering technique of OpenGL to accelerate the tracing process of rays from antenna. To improve the accuracy...
An accelerated Integral Equation Method (IEM) for the backscattering of the 3-D time-varying overturning wave crest model is presented in this paper. The investigation of the backscattering of the 3-D time-varying overturning wave crest model is very meaningful for the study of sea spikes. For the IEM, the governing equations for the tangential surface fields on a dielectric surface can be written...
This paper focuses on two integration algorithms used for pseudo-dynamic test, explicit New mark algorithm and implicit alpha-C algorithm. The comparison study between the test and simulation results shows that: the non-uniform distribution of mass, restoring force characteristics and higher frequency vibration modality are simulated more accurately using the alpha-C algorithm than using explicit...
