Selecting this option opens the Simulation panel on the right of the window:
In this panel, the user can set the main parameters of the simulation:
- Frequency: To set the simulation frequency. The following parameters may be modified:
- Enable Sweep: select this option to simulate a range of frequencies.
- Units: to set the magnitude of the frequency. Hz, KHz, MHz, and GHz are available.
- Initial frequency: the first step in the frequency range, in the selected Units. If the frequency Sweep is disabled, this value coincides with the simulation frequency.
- Final frequency: the last step in the frequency range, in the selected Units. This parameter may be only modified when the frequency Sweep is enabled.
- Samples: number of frequency samples to be analyzed on the frequency Sweep. This parameter may be only modified when the frequency Sweep is enabled.
- Simulation Type: The user can select a type of simulation to obtain certain results.
- Selecting None type, the user will obtain default results as radiation pattern, current density, charge density, near-field observation, etc.
- Selecting Multipole type, the user will obtain default result and multipole files that can be used in other simulation as antenna input. A multipole consists in a division on parallelepipedal regions of the simulated case. Each region contains the whole information such as its geometry and its currents, so this representation is more accurate than the radiation pattern files. The multipole files only will provide accurate results in further Far Field simulations.
- Selecting Radiation Map type, the user will obtain default results and the radiation map results. This simulation enables the Radiation Map results, which show the scattered field by each region in the observation direction.
- Selecting Delay Process type, the user will obtain default results and the delay process results. This simulation enables the Delay Process results, which show the interferences introduced in a given input Signal in the time domain by each region in the observation direction.
- Selecting S-Parameters, the user will obtain S-Parameters results of coaxial feed antennas and waveguides. Note that with simulation type, the only provided results after the simulation process are the S-Parameters. When this simulation type is selected, the S-Parameters Settings button is enabled to modify advanced parameters that affect to the waveguides analysis. The following parameters may be configured:
- Lambda guide factor: it is the value for dividing the wavelength and then obtaining the distance to extend the main port in the analysis process. The higher parameters result in shorter extensions.
- Lambda guide factor for short-circuiting: it is the value for dividing the wavelength and then obtaining the distance to extend the ports that are not fed in the analysis process. The higher parameters result in lower extensions.
Advanced S-Parameters setting
The Window Size (lambda) parameter specifies the number of lambdas which defines the size edge of the generated regions in multipoles output files. This option only may be modified when a Multipole or Radiation Map simulation types are selected.
