Solution.s_parameters

Description​

Retrieves the scattering parameters (S-parameters) computed by the electromagnetic solver over the simulated frequency range.

S-parameters describe the reflection and transmission of signals between the ports of an electromagnetic model. They are represented as complex values, providing both magnitude and phase information at each simulated frequency.

The method returns an SParameters object, which provides access to individual S-parameters and methods for plotting their frequency responses.

Syntax​

sparams = obj.s_parameters()

obj

obj A Solution object returned by HighFrequency.solve.

sparams = obj.s_parameters()

sparams = obj.s_parameters() Retrieves the computed S-parameters and returns an SParameters object containing their complex values and corresponding frequency data.

Output Arguments​

sparams

Type SParameters

SParameters object containing the complex scattering parameters and their corresponding frequency values in Hz.

Examples​

sparams = solution.s_parameters()

# Retrieve the reflection coefficient at port 1
s11 = sparams.get(1, 1)

# Access the corresponding frequency values
frequencies = sparams.frequency

# Plot the reflection coefficient
sparams.plot(port_out=1, port_in=1)

Notes​

S-parameters are available for models with configured excitation ports. The returned data corresponds to the frequencies used in the simulation.

Port numbering starts at 1 when using SParameters.get() and SParameters.plot().
