Hi,

I am simulating a simple bow-tie antenna on dielectric material in CST studio. The antenna is matched to 50 Ohm at ~500GHz. When I plot the power view of the structure I expect to see that "accepted power = radiated power + power loss". However, I get a different graph in which the power is apparently unbalanced. The attached picture shows the power view with a monitor at 500 GHz.

In CST help files there should be also "loss in lumped-elements" component which I dont get as an output in my simulation.

I would appreciate your help with this.
