Study on the Comparation of Field-Wire Coupling Efftect for Long Wire in UWB with HEMP

In order to study the problem of field-wire coupling effects for long wire in UWB and HEMP in detail,and to contrast the field-wire coupling effects in HEMP with UWB,this paper deduces an applied formula which can apply to calculation by program effectively according to Agrawal and Vance models.The paper writes a Matalb program based on the formula,and applies the program to calculate field-wire coupling effects in UWB and HEMP.It gets the rule of the two intense electromagnetic fields.The result show that both UWB and HEMP can drive high current pulse on wire,and can drive intensity voltage pulse at end of wire;the response of UWB is weak to the response of HEMP at similar conductions.The field-wire coupling effects of UWB and HEMP have some similarities,and also have some different characteristic.
