lumped resistor in CST Microwave Studio

hi everyone

I'd really appreciate some help with following question: I'm simulating a complex meta-material absorber (CMMA) and i want to enter 2 resistors and 2 capacitors in it. i wonder how i can do it. i thought of wave guides but hadn't tested it and don't know how to do it.

The MMA is one in the top link. Resistors and capacitors are to be placed in the discreet points of outer circle. (I know how to pick points, edges, etc)

p.s. it's my 1st time writing here so i hope to helped & helpful.

I found my answer an it was a really easy one. It's just to pick the two point U want your lumped element between and then use lumped element bottom on the simulation tab, you'll then be able to insert resistance, capacitance or inductance. Or even insert a diode.

simulation-->pick point/edge mid(pick 2 points you want the element between)-->lumped element

Right. CST is very easy to add port or lumped elements.

Hi All,
I try to design SRR antenna with additional capacitance in between gap so that it will match my 50 ohm input impedance.But it doesn't show any effect of S11 when i change the value of capacitance. Can anyone help me on this matter.Here I'm attaching the CST 2014 file. Thank you in advance.
