Knowledge articles provide in-depth discussions on specific topics.

Far Zone

Far zone radiation patterns are a common antenna design metric. These articles explain how far zone results are generated from the near-field simulation space, as well as discuss topics related to antenna arrays.


There are numerous excitations in XFdtd. Knowing the difference between them and discerning when each should be used is essential for effective simulation.

Specific Absorption Rate

SAR results are sensitive to the grid's alignment with phantom geometry. Understanding the background information and applying that knowledge is fundamental to producing reliably accurate results.
