    Design a horn-fed offset parabolic reflector antenna with a diameter of 1 m, focal length 0.9 m, clearance height 0.1 m, radiator aperture 68 mm, and surface error 1 mm.

    ant = reflectorCalculator(Diameter=1,FocalLength=0.9,ClearanceHeight=0.1, ...
    RadiatorAperture=0.068,SurfaceError=1e-3)
    ant = 
  reflectorCalculator with properties:

            Diameter: 1
         FocalLength: 0.9000
     ClearanceHeight: 0.1000
            FeedType: 'singlefed'
    RadiatingElement: 'horn'
    RadiatorAperture: 0.0680
           ScanAngle: 1
        SurfaceError: 1.0000e-03
            FeedLoss: 0

    Create a customDualReflectors object for the full-wave analysis.

    cd = createAntenna(ant,10e9)
    cd = 
  customDualReflectors with properties:

             Exciter: [1×1 horn]
       MainReflector: [166×3 triangulation]
        SubReflector: []
     ReflectorOffset: [0 0 0]
          FeedOffset: [0.9710 0 -0.0679]
       ReflectorTilt: 0
    RemeshReflectors: 1
                Tilt: 0
            TiltAxis: [1 0 0]
                Load: [1×1 lumpedElement]
          SolverType: 'MoM-PO'

    Plot its radiation pattern at 10 GHz.
