However, t is model will require extensive com- puter time for simulation c aracteristic of ig power microwave long pulse propagation. In t is paper, we present a new refined model w ic requires less computational complexity for simulation c aracteristic of ig power microwave long pulse according to conservation of energy. Numerical simulation s ows good a- greement between t e envelopes of t e two models.
