s parameters metamaterials
i've worked on FEKO but with direct feed on ports, no idea about finding out s parameters without defining ports , but i feel its not feasible , u need to define the ports.
or u can place that structure in waveguide and the define the ports and calculate the sparameters
antenna gain: voltage or power
Gain can be in both terms dBi and dBd
if u r measuring in refrence to istropic antenna(which is the norm) then its dBi
and if refrence with sm directive antenna then dBd
Data sheets show dBi reading
