If the project workspace contains an array of rectangle strip objects or PEC via objects, the array object will also be listed as an eligible object for lumped element placement. A lumped element will then be placed on each element of the array. All the lumped elements will have identical direction, offset, resistance, inductance and capacitance values. If you define an active lumped element, you can prescribe certain amplitude and/or phase distribution to the gap sources just like in the case of gap and probe sources. The available amplitude distributions include '''Uniform''', '''Binomial'''''', Chebyshev''' and '''Data File'''.
'''{{Note that the |The impedance of the lumped circuit is calculated at the operating frequency of the project using the specified R, L and C values.''' As you change the frequency, the value of the impedance that is passed to the Planar MoM engine will change.}}
