| Horn Antenna |
 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®.
|
| Waveguide |
 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.
|
| Horn Antenna Using MPI |
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.
|
| Spherical Lens Geometry |
 See the results of a complex 17 wavelength-diameter spherical dielectric lens designed in AutoCAD and run in XFdtd®.
|
| Photonic Crystal Array Simulation |
 The containment of the fields within the waveguide is clearly visible as the signal turns the corner and continues.
