    Syntax

    [epsr,losstang,f] = getMaterialProperties(object)
    [___] = getMaterialProperties(___,frequency)

    Description

    [epsr,losstang,f] = getMaterialProperties(object) calculates and returns the dielectric properties of the specified material object at the analysis frequencies of the parent antenna catalog element.

    [___] = getMaterialProperties(___,frequency) calculates and returns the dielectric properties of the material object at the specified frequencies.

    Output Arguments

    collapse all

    Relative permittivity of material, returned as a numeric M-by-F matrix. M is the number of materials in the dielectric object and F is the number of frequencies.

    The relative permittivity is calculated based on the specified frequency model of the dielectric object.

    For the Constant and MeanDjordjevicSarker frequency models, the matrix is of size M-by-1.

    For the DjordjevicSarker and TableDriven frequency models, the matrix is of size M-by-F.

    Data Types: double

    Loss tangent of the material, returned as a numeric M-by-F matrix. M is the number of materials in the dielectric object and F is the number of frequencies.

    The loss tangent is calculated based on the specified frequency model of the dielectric object.

    For the Constant and MeanDjordjevicSarker frequency models, the matrix is of size M-by-1.

    For the DjordjevicSarker and TableDriven frequency models, the matrix is of size M-by-F.

    Data Types: double

    Frequency used for dielectric property calculation, returned as a numeric scalar or vector.

    Example: 70e6
