“…ANNs are information processing systems that have been widely applied in the RF/microwave modeling tasks as an unconventional alternative. Through a process called training, ANNs have the ability of fitting any nonlinear behavior of passive and active component/circuit from experimental data and generating an ANN model function thatcan be used to describe the port-characters of that component/circuit[ 172,173] . The multi player perceptron (MLP) is a popularly applied neural network structure.…”
