The first step of planning a planar MoM simulation is defining your planar structure. This consists of the background structure plus all the finite-sized metal and slot trace objects and possibly embedded metal or dielectric objects that are interspersed among the substrate layers. The background stack-up next step is defined in to decide on the Layer Stack-up dialogexcitation scheme. If your planar structure has one or more ports and you seek to calculate its port characteristics, which automatically opens up as soon as then you enter have to choose one of the [[Planar Module]]. The metal and slot traces and lumped source types or a de-embedded object sets are listed in the Navigation Treesource. Before you run a planar MoM simulation, which you also shows all need to decide on the geometrical (CAD) objects project's observables. These are the simulation data that you draw in expect EM.Picasso to generate as the project workspace under each object group outcome of the numerical simulation. If you run a simulation without having defined any observables, no data will be generated at different Z-planesthe end of the simulation.

The next step is to decide on the excitation scheme. If your planar structure has one or more ports and you seek to calculate its port characteristics, then you have to choose one of the lumped source types or a de-embedded source. If you are interested in the scattering characteristics of your planar structure, then you must define a plane wave source. Before you can run a planar MoM simulation, you also need to decide on the project=== Planar Module's observables. These are the simulation data that you expect [[EM.Cube]] to generate as the outcome of the numerical simulation. [[EM.Cube]]'s [[Planar Module]] offers the following observables:Simulation Modes ===

* Current Distribution* Field Sensors* Far Fields (Radiation Patterns or Radar Cross Section)* Huygens Surfaces* Port Characteristics* Periodic Characteristics If you run a The simplest simulation without having defined any observablestype in EM.Picasso is a single-frequency analysis. In this mode, no data will be generated the planar structure in your project workspace is meshed at the end center frequency of the simulationproject. Some observables require a certain type After the completion of excitation source. For example, port characteristics will be calculated only if the project contains a port definitionplanar MoM simulation, which in turn requires the existence a number of at least one gap or probe or de-embedded source. The periodic characteristics (reflection and transmission coefficients) data files are calculated only if generated depending on the structure has observables you have defined in your project. An analysis is a periodic domain and excited by a plane wave sourcesingle-run simulation. === Planar Module's Simulation Modes ===

The simplest simulation type in [[EM.Cube]] is an analysisPicasso offers a number of multi-run simulation modes. In this modethose cases, the planar structure in your project workspace is meshed at the center frequency of the project. [[EM.Cube]] generates an input file at this single frequency, and the Planar MoM simulation engine is run oncemultiple times. Upon completion of the planar MoM simulationAt each engine run, certain [[parameters]] are varied and a number collection of simulation data files are generated depending on the observables you have defined in your project. An analysis is At the end of a singlemulti-run simulation, you can graph the simulation results in EM.Grid or you can animate the 3D simulation data from the navigation tree. For example, in a frequency sweep, the frequency of the project is varied over its specified bandwidth. Port characteristics are usually plotted vs. frequency, representing your planar structure's frequency response.
