Abstract :
A model of the termination of the GTEM (GigaTEM) cell is discussed. The termination is effective over a very large band owing to the combination of resistors, acting at low frequencies up to ≈100 MHz, and of tapered absorbers, acting at frequencies higher than 100 MHz. The combined effect of both mechanisms is examined by using a transmission line model for low frequencies and a local mode expansion for higher frequencies
