The same horn antenna geometry shown in other XFdtd^® examples on our web site is used here to demonstrate the ability of the MPI version of XFdtd.

The containment of the fields within the waveguide is clearly visible as the signal turns the corner and continues.

See the results of a complex 17 wavelength-diameter spherical dielectric lens designed in AutoCAD and run in XFdtd^®.

In this example XFdtd^® 6 is used to make calculations for an open-flanged waveguide with a specialized dielectric slab window material used to match the waveguide impedance to the impedance of a liquid located at the waveguide flange terminus.

An optimum gain pyramidal horn antenna (see Antenna Theory and Design by W. Stutzman and G. Thiele, John Wiley & Sons, New York, 1981, pgs 413-415) was simulated using XFdtd^®.
