EM3DS 8.0 2006 (电磁三维软件)
这是一款意大利产出的电磁三维软件EM3DS (Electromagnetic 3D Solver)。
它是新奇、全功能、频率领域充足波浪仿真工具，有效地完成类似平面结构的化验。关于复杂的底层的专门平面结构，限定导电品的厚度和绝缘体的不连续性被视为防止危险的发生。因此，提供全面三维工具应用于EM3DS。
EM3DS使用 method-of-moments (MoM)技术，提供理想的2.5 与 3D仿真能力。使设计者可以对微系统电磁效果进行快速的、可定制的模拟。这个仿真工具可以作为CoventorWare的补充，用于RF，microware，及其他MEMS 器件。同时，EM3DS也可以作为一独立的产品来使用。
相对于传统的有限元法，method-of-moments适合于高纵横比的结构（最大特征尺寸与最小特征尺寸比例很大）。method-of-moments能在纵横比是一重要考虑因素的地方，比如平板结构，进行更快的2.5 与 3D 仿真（比传统工具快50%-300%）。
鼠标轻轻一点，Coventor公司的EM3DS就可以由非常详尽的3D仿真转换到2.5D仿真。EM3DS非常适合处理整合了绝缘层、薄金属、以及绝缘夹杂物等等的复杂结构。
软件具有前后处理能力，可以进行linear circuit analysis, network parameters, Smith charts, S-parameters and SPICE extractions。能够输入的文件格式包括GDSII, AutoCAD DXF 和 BMP。

or it is necessary to gather 100 message! ?
yeah
you are right
you can got it when you gather 100 credit
最后一个包要有一定积分才能下，可惜积分不够啊
这不是一个独立软件吗，怎么会是ADS的呢？:27bb
EM3DS (ElectroMagnetic 3D Simulator)is an integral equation-based full wave simulator, using an approach called Generalized Transverse Resonance Diffraction (GTRD), developed by MEM (Microwave and ElectroMagnetics) Research. Details about the general technique are available in a number of source, including the book “Advanced Electromagnetic Analysis of Passive and Active Planar Structures”, by T. Rozzi and M. Farina (IEE Press 1999) and in the paper “A 3-D Integral Equation-Based Approach to the Analysis of Real Life MMICs: Application to Microelectromechanical Systems”, by M. Farina and T. Rozzi (IEEE MTT December 2001).
This simulator accounts for finite-thickness, finite conductivity real conductors/dielectrics by using volume currents. The structure is still layered -and defined layer-by-layer, much like a standard process to realize integrated circuits or printed circuit board- but current induced in conductors appears to be arbitrarily oriented (Jx, Jy and Jz are always present in the 3D mode; as consequence the total current may have arbitrary orientation even over sides of a thick conductor). This allows EM3DS to fully model also dielectric discontinuities, including Dielectric resonators, which are out of the scope of traditional so called 2.5D solvers, namely solvers modeling either flat planar circuits by exploiting xy currents and vertical conducting posts (vias) by using z currents alone.
Moreover, the ability to handle conductor thickness, which is usually not very important in standard PCB design where substrate losses are dominant and the structures are very large with respect to the metallization thickness, it may fundamentally affect results in MMIC design, where strips may be a few microns thick and wide. Metal thickness is also important in waveguide filters: consider e.g. that in single cavity WR90 resonator, neglecting the iris thickness may produce a resonant frequency shift of over 5%.
EM3DS is mainly aimed at the analysis of planar structures, but due to its 3D nature it may be used also to address some other problems, like e.g. the modeling of some class waveguide filters with arbitrary thick, possibly lossy, irises.
Actually EM3DS embodies in fact 2 EM Solvers – 2.5D and 3D. Which solver to use is rested upon the designer’s choice and is a simple click to shift the mode of operation. It means that by simple click onto your 3D structure, you obtain 2.5D geometry and you can simulate as 2.5D and compare with your 3D simulation. The speed is increased in 2.5D mode by a factor varying from 50% up to more than 300%: the more the structure is complex, the larger is the time saved. The 2.5D mode comes as a limit of the 3D formulation, keeping several attracting capabilities of the 3D mode.
EM3DS comes with a complete set of tools. The most important is maybe the panel for global parameters/variables: the panel allows you to define variables, and to parameterize the geometrical features of your objects. This means that you can modify and optimize your design without painfully entering new dimensions shape by shape. The optimization can either be manual (the designer does the work) or exploit the embedded optimizer. Variables can be modified also accessing a "tuner", a set of sliders varying those variable indicated as tunable in the optimizer panel. Variables can also be accessed through a pascal "script", namely by writing a pascal code directly in EM3DS.
As to the speed, EM3DS always performed very well thanks to its Asymptotic Estimator, which performs a full simulation only at the first frequency point, while reusing most of the information for the analysis at the remaining frequency points. Moreover, since version 7 is available a new powerful device, SmartFIT: this algorithm adaptively drives the EM solver, generating a frequency list within the user-selected band. At the end it estimate the response all over that band, in tents or hundreds of points. Of course it is possible to exploit a rational interpolator even in post-processing, but without the same guarantee to get good results.
The new release, version 9, adds several completely new features, such as internal planar ports, antenna functions (namely sense layer to see the E-field and to evaluate radiated far field, both in standard polar diagrams, or in 3D surfaces), object oriented pascal scripting, tuner, enhanced editing etc.
Since ver 6.0 EM3DS was the first tool allowing the full-wave modeling of FETs in linear regime: this is accomplished through the insertion of distributed controlled current sources. EM3DS 6.0 provides for the materials’ constitutive parameters to be frequency dependent, and may further be specified by the user through analytical expressions (formulas). Every parameter in EM3DS can conveniently be input as a valid algebraic expression, (for instance: sin(3.5)), and is fully evaluated (calculated) by EM3DS, thus facilitating the overall process and avoiding using calculators.
Unlike some other commercially available tools, when entering the geometry, EM3DS does not pose any requirement on the grid.
The only event when grid is desirable, and in fact EM3DS can make use of it, is during the drawing, where it offers additional flexibility.
As stated above, EM3DS comes integrated with several tools, aimed to ease interfacing with other CAE tools. As to the pre-processing step, filters allowing importing GDSII and DXF (as well as general bitmaps) are available. The post-processor includes a Spice Model Extractor, a simple Linear Circuit Simulator, tools for saving animations (GIF, AVI), link to AVI files via multimedia documents, exporting graphs (plots, Smith Charts), data files (Touchstone), to see the interaction between a user-defined magneto-static field and RF currents flowing across an object etc.
Nonetheless for MEM Research it is imperative to look for partnerships in order to better exploiting the EM3DS power. This is why in the past EM3DS 5 was also fully integrated as Electromagnetic Module in the multi-physic package by Corning Intellisense, Intellisuite®.
Currently, EM3DS is companion of CoventorWareTM, by Coventor, leading company in the MEMS software development: EM3DS was carefully selected by Coventor thanks to its remarkable achievements.
By the same token EM3DS has the ability to be accessed directly from the AWR Microwave Office (since version 6 of MWO) suite. This means that AWR’s customers are able to see EM3DS as an electromagnetic engine, still using Microwave Office editor and post-processing capabilities.
