AXIEM

EM analysis for planar structures

AXIEM solves planar structures using the method of moments: transmission lines, passive components, coupling, and large antennas. The analysis is launched directly from the design in Microwave Office.

The challenge

It costs you time and money

  • Component models become inaccurate at your operating frequencies
  • Coupling between structures is missing from the circuit model
  • EM analysis requires moving the design to another tool
  • Support responses that take days

The solution

We give you control back

  • The structure calculated exactly as drawn
  • Coupling between lines and components included in the results
  • Analysis launched directly from the design, without export
  • Local hotline with responses from a specialist on the same day
Martin Lange

HOW IT WORKS

Method of moments tailored for planar geometry

Built for planar structuresThe method calculates current on conductive surfaces rather than filling the entire volume with a mesh. This makes it fast and accurate specifically for the geometry found in RF copper.
The result is a modelThe analysis provides S-parameters for the structure, which are used directly in the circuit simulation. It is not just an image, but a functional model.
Within the same design environmentSelect the structure in the layout, and the result returns to the same place. No export, no rebuilding of geometry.

VALUE

AXIEM covers the planar structures in RF design

From transmission lines and passive components to antennas and arrays, solved exactly as drawn.

What it calculates

Planar structures make up most of the copper in an RF design.

Transmission lines and transitionsWhere standard models no longer apply
Passive structuresCouplers, filters, and matching networks
Antennas and patch arraysIncluding large-scale designs

The method

The choice of method determines what can be solved quickly and what can be solved accurately.

Method of momentsCurrent on conductors rather than volume meshing
Built for planar geometryFast and efficient for its intended purpose
Automatic meshingGenerated directly from the structure

Into the circuit

An EM analysis is only valuable when the result can be directly applied in simulation.

In the workflow

The analysis that actually gets run is the one that fits seamlessly into the workflow.

The boundary to 3D

Implementation

How AXIEM works in practice

Cadence provides the solver. Nordcad helps you apply it to the right structures.

Select the structures that matter

Not everything requires electromagnetic simulation. We advise on what is essential to include and what unnecessarily consumes compute time.

The setup must be repeatable

EM analysis is used to compare results before and after changes. This requires a consistent setup, and that is one of the areas where we assist.

Local expertise and ongoing support

You gain access to specialists with hands-on EM analysis experience who can review results together with you.

FAQ

Frequently Asked Questions

When the geometry is planar. AXIEM is designed for planar conductors and offers the highest performance there. As soon as the structure involves a true third dimension — such as a connector, transition, or housing — Analyst is the appropriate choice.

The tools are integrated within AWR, and AXIEM is typically used on structures directly from a Microwave Office design. If you only need to solve a standalone structure, we evaluate what makes technical sense before any purchase.

Large planar antennas and arrays are precisely what this method is built for. In practice, the limit is set by the hardware and how finely the structure needs to be meshed — this is one of the aspects we can evaluate for your specific project.

AXIEM is planar and integrated into the RF flow. Clarity is a full 3D solver for electronic simulation, typically used for interconnects and packages in digital designs. They address different challenges, and the choice generally depends on the design environment you are working in.
