Return losses of an antenna complex
Case Comparison and Verification
EastWave is a full-wave Computational Electromagnetics (CEM) software for both electromagnetic and photonic applications, whose solvers are based on the Finite-Difference
Time-Domain algorithm. Particularly for electrically large engineering problems, EastWave has an outstanding superiority in saving computational time without losing accuracies.
Moreover, EastWave offers a Physical Optics (PO) solver and an FDTD/PO hybrid solver for extremely large engineering problems. The superiority of saving computational resources makes automatic optimization workable in many cases which might be considered impossible with traditional methods.
EastWave features a variety of predefined workflows which greatly simplifies the workflows for engineers and researchers. These workflows include Standard,Transmission/Reflection, RCS, Antenna, Phased Array, Radome, Radar Target Imaging, Microwave Network and Field Difference Comparison.
EastWave has been widely applied in the analysis of microwave/RF systems (antenna array, radome, RCS, FSS, EMC/EMI, anechoic chamber, RF signal coverage, etc.) and photonic systems (laser, LED, metamaterial, photonic crystal, optoelectronic devices, etc.).
This document presents seven real-world application cases, in order to demonstrate the accuracy and efficiency of EastWave in comparison with other CEM solutions (such as MoM, FEM) or experimental data.
RCS characteristics of a sphere-conical object
Object 1 is featured with a solid sphere-conical model of 324 mm×133 mm×133 mm dimensions, illuminated by a VV-polarized incident plane wave (θ=90 °, φ=0 °) normal to its
apex, under work frequency 0.5 - 12.5 GHz (Figure 1). Figure 2 depicts the comparison of RCS characteristics between EastWave and MoM (Figure 2). Table 1 lists the computational efficiencies and memory consumptions from EastWave and MoM.
