    Syntax

    flag = isPolarizationCapable(ris)

    Description

    flag = isPolarizationCapable(ris) returns a Boolean value, flag, indicating whether the ris array supports polarization. A RIS array supports polarization if it can create or respond to polarized fields.

    Test if a RIS array of short-dipole antennas is polarization capable. Assume the array operates at 300 MHz.

    fc = 300e6;
c = physconst("LightSpeed");
lambda = c/fc;
d = 0.5*lambda;
ris = phased.RectangularRIS( ...
    UnitCell=phased.ShortDipoleAntennaElement(), ...
    Size=[20 30],Spacing=[d,d]);
isPolarizationCapable(ris)

    Reconfigurable intelligent surface, specified as a phased.RectangularRIS System object.

    Output Arguments

    collapse all

    Polarization flag, returned as false or true. If false, a RIS array does not support polarization. If true, the array supports polarization. A RIS array supports polarization if its elements support polarization.
