Since the center frequency of the project is 1GHz, the operating wavelength is:

The boundary Conditions at the six faces of the computational domain can be set by selecting the menu item Simulate ï Computational Domain ï Boundary Conditions⦠or by right clicking on the âBoundary Conditionsâ item in the âComputational Domainâ section of the Navigation Tree. By default, EM.Cubeâs [[FDTD Module]] assumes an open-boundary physical structure. All the six boundaries default to PML, or Perfectly Matched Layer, which you are going to maintain for this tutorial lesson. But the dropdown lists allow you to also choose PEC, or a Perfect Electric Conducting boundary, or PMC, a Perfect Magnetic Conducting boundary.
