STATIC STUDY OF COMPLEX PLANAR STRUCTURES APPLICATION TO THE EXCITATION MODELING OF LINES ANALYZED BY THE FINITE-DIFFERENCE TIME-DOMAIN METHOD

In this paper, a static electromagnetic study of planar structures is effected. The determination of electric and magnetic field distributio n in a line cross-section is discussed. This electric and magnetic fie ld distribution is used to deduce the characteristic impedance of this line. The second application concerns the simulation of the line feed when a transient analysis using the finite difference time domain met hod is used to analyse the line behaviour. In the case of a microstrip line, this new excitation method is compared to two excitations which are generally used.
