2-5
Perfect E and Perfect H/Natural
Ideal Electrically or Magnetically Conducting Boundaries
‘Natural’ denotes Perfect E ‘cancellation’ behavior
Finite Conductivity
Lossy Electrically Conducting Boundary, with user-provided conductivity and
permeability
Impedance
Used for simulating ‘thin film resistor’ materials, with user-provided resistance
and reactance in /Square
Layered Impedance
Screen Impedance
Radiation
An ‘absorbing boundary condition,’ used at the periphery of a project in which
radiation is expected such as an antenna structure
Symmetry
A boundary which enables modeling of only a sub-section of a structure in which
field symmetry behavior is assured.
“Perfect E” and “Perfect H” subcategories
Lumped RLC
Master and Slave
‘Linked’ boundary conditions for unit-cell studies of infinitely replicating geometry
(e.g. a slow wave circuit & an antenna array)
PML (Perfect Match Layer)
