Guangzhou, China: February 26, 2020 – After the debut of ZWSOFT’s brand-new CAE software ZWSim-EM, a 3D full-wave electromagnetic simulator, it has aroused the interests of many users in related fields. Now, its SP version is ready with practical new features and enhancements, taking a step forward to an excellent EM simulation solution.
Plane Wave Excitation
Plane Wave is used to simulate the case in which the distance between the incident wave and the object to be observed is infinite. It is usually applied to the simulation of RCS.
In ZWSim-EM 2019 SP, you can set the zero phase point, the direction of incident wave, the sweeping ways including Horizontal, Vertical and 3D, and the types of polarization including Linear, Circular and Elliptical. After setting, the plane wave excitation can be checked intuitively in the View Area.

RCS (Radar Cross Section) Analysis
RCS, the cross-sectional area of radar echoes, can now be analyzed in this new version, enabling radar designers to simulate and predict radar signatures. It can be expressed by the equivalent area of the target radiation. Representing the strength of radar return and the characteristics of electromagnetic scattering, it plays a role in radar stealth technology, aircraft, ballistic missiles, etc. What’s more, with Plane Wave Excitation, the radar signature of both mono-static and bi-static RCS can be analyzed.

Customizable Dielectric Priority
In the previous version, only the common case that conductors intersect dielectrics could be handled with the default processing order PEC>Conductor>Dielectric. Now you can customize the priority of dealing with different materials when dielectrics intersect one another, making the pre-processing more convenient and user-friendly.

Impedance Calculator
The new Impedance Calculator enables you to get relevant data of impedance quickly. After inputting the geometric size (including length, width, height, thickness and rough), you can get the corresponding electrical parameters (including Z0 and angle) of the impedance, and vice versa.
Moreover, effective relative dielectric constant, skin depth, conduct loss and dielectric loss can also be calculated by a few clicks. After calculating, the transmission lines can be inserted into the model by Build 3D, and simulated together afterwards.

Besides, High Performance Calculation is available by making use of multi-core and parallel computing, greatly accelerating your simulation process especially for complicated models and numerous meshes. What’s more, mesh generation for feeding ports, ordinary fine structures and conformal slot structures is also further enhanced, bringing forth more accurate simulation results.
