    This example obtains the number of elements on a 20-by-30 rectangular Reconfigurable Intelligent Surface (RIS) operating at 300 MHz. Elements are spaced one-half wavelength apart.

    fc = 300e6;
c = physconst("LightSpeed");
lambda = c/fc;
d = 0.5*lambda;
ris = phased.RectangularRIS( ...
    UnitCell=phased.CosineAntennaElement(CosinePower=2), ...
    Size=[20 30],Spacing=[d,d]);
n = getNumElements(ris)
    n = 
600
