- is the power radiated out of the system (emitter and antenna) that is collected in the far field. This can be calculated in FDTD simulations using a transmission box monitor enclosing the entire system.
- dipolepower or a transmission box monitor enclosing the dipole alone. is the power absorbed by the antenna. In FDTD simulations it can be calculated directly with a transmission box monitor enclosing the antenna only. However, it is more convenient to calculate the power radiated by the emitter in the presence of the antenna and then use . The power can be found using either the script command
Can you explain what is the difference between Pdip and Prad. They should be the same if the material is non-absorbing. If there is a non-radiative channel how to calculate it? Whenever we calculate collection efficiency, it can be defined as power collected through the lens divided by the total available power for the collections or dipole power. If a non-radiative channel exists then the total available power for the collections and dipole power are different. How to get an idea about the nonradiative channel?

Hi, sorry I don't understand, could you please figure out where you find the Pdip and Prad definition? From our web example?
