Palo Alto, Calif.Do dimension-critical microwave components, feedlines, antennas, and stripline layouts scare you? If so, you're not alone. Help's on the way.
If you're designing RF circuits, especially critical microwave frequency systems, check out Agilent Technologies Inc's. soon-to-be-released Electromagnetic Design System (EMDS) software. Get in on a beta test program, too.
The company claims EMDS will be the leading performance tool at its price point when it debuts in July. What's more, the EMDS integrates with Agilent's existing RF and microwave circuit design and simulation flow.
Using EMDS, you’ll be able account for three-dimensional (3-D) electromagnetic (EM) effects in passive structures such as component-level bond wires, connectors, packages, and microwave machined parts.
The EMDS system supports analysis and visualization of EM effects, to give you insight into performance. You can use it to make informed decisions and adjustments before physical prototyping. This can reduce or eliminate costly design iterations, and can save months in a typical product-development cycle.
It’s Priced Right
Because typical high-end 3-D EM simulators demand a higher price than common circuit-simulation tools, many RF engineers skip EM analyses, relying instead on best guesses regarding 3-D EM effects on circuit performance.
In contrast, Agilent claims its EMDS package will provide 3-D EM at a price comparable with leading circuit-simulation tools, so more designers can afford to have it on their desktops.
In use, EMDS users will need little background in electromagnetic field theory to operate and achieve accurate and meaningful results. The software even handles arbitrarily-shaped 3-D passive structures.
EMDS provides support for conductors, resistors, isotropic dielectrics, anisotropic dielectrics, and isotropic and anisotropic linear magnetic material modeling. An unlimited number of ports can be specified, enabling simulating multi-I/O design applications, such as packages.
The software also permits electric field and magnetic field modeling, giving you nifty color visualization of EM fields in your design. It also supports absorbing boundary condition (free space) for antenna modeling.
Agilent also says using EMDS will give you full-wave EM-accuracy for first-pass design success. The system also ensures multi-mode impedance and propagation constants that overcome single-mode modeling limitations inherent in some EM modeling tools.
Antenna parameters (such as gain, directivity, polarization, and so on), can be modeled, giving you better insight into antenna design. Micro strip, stripline, filters, couplers, spiral inductors, via holes, air bridges, meander lines, and other multi-layer structures are also supported.
You can also use EMDS to test for the effects of launches and transitions in coax-to-microstrip, or microstrip-to-stripline, for example. Similarly, the software lets you experiment with components such as ceramic filters, surface-mount parts, waveguide filters, couplers, power splitters, combiners, and mode converters.
To aid in analyzing your designs, EM field animation and dynamic rotation of structures can be performed simultaneously. You can choose shaded plots, contour lines, or vectors, and 3-D far-field plots can illustrate beam shapes in both azimuth and elevation on a single plot.

This first release of the EMDS provides basic design-flow integration with Agilent's Advanced Design System (ADS), letting you bring layout designs from ADS into EMDS for full 3-D analysis. Agilent plans to include increasing levels of integration with ADS and with the company's GENESYS environment.
GENESYS, from the former Eagleware-Elanix product line, is a single integrated electronics design automation (EDA) environment for RF and microwave applications.
For its part, the ADS offers a set of front-to-back simulation and layout tools and instrument links for RF and microwave IC design, in a single integrated design flow.
Agilent says its EMDS will be available to selected beta-test users beginning next month. Pricing starts at about $15,000.
