  3. From the Plot Name field, enter a name for the plot.
  4. From the Plot field, choose from the available options.

    The far field quantities measure the product r*E, where r is the radial distance from the origin and E is the electric field vector. For far fields, r*E does not depend on r; or equivalently, E is proportional to 1/r. Also, for far fields the radial (r) component of the E field is zero. The units of r*E are Volts.

    ePhi, eTheta

    spherical (phi, theta) components of the quantity r*E. These are complex numbers.

    eTotal

    eTotal is a real number, and is the square root of the sum of the magnitudes of the vector components of r*E. It can be expressed either as:

    or

    eX, eY, and eZ

    Cartesian (x, y, z) components of the quantity r*E. These are complex numbers.

    ELeft

    The dominant component for a left-hand, circularly polarized field.

    ERight

    The dominant component for a right-hand, circularly polarized field.

    MaxEX

    A real-valued quantity. It is the maximum value (across all values of phi and theta on a sphere) of the magnitude of the x-component of r*E.

    MaxEY

    A real-valued quantity. It is the maximum value (across all values of phi and theta on a sphere) of the magnitude of the y-component of r*E.

    MaxEZ

    A real-valued quantity. It is the maximum value (across all values of phi and theta on a sphere) of the magnitude of the z-component of r*E.

    MaxEPHI

    A real-valued quantity. It is the maximum value (across all values of phi and theta on a sphere) of the magnitude of the phi-component of r*E.

    MaxETheta

    A real-valued quantity. It is the maximum value (across all values of phi and theta on a sphere) of the magnitude of the theta-component of r*E.

    MaxETotal

    The maximum value (across all values of phi and theta) of eTotal.

    MaxELeft

    Maximum values for the dominant component for a left-hand, circularly polarized field.

    MaxERight

    Maximum values for the dominant component for a right-hand, circularly polarized field.
