    Excitation of the Structure

    Updated

    If a discrete voltage source is placed at the i-th segment, the corresponding element in the voltage matrix is simply equal to the voltage of the generator. Thus,

    Eq. (1)

    When an incident plane wave is used as the excitation, each wire segment is excited by the incoming field, which has the form:

    Eq. (2)

    where k is defined by the direction of propagation, so that |k| = k is the wave number, and r is the evaluation point, Fig. 1. The elements of the voltage matrix are then defined by:

    Eq. (3)

    where the integration is performed over the m-th segment, and the vectors r(s) and T(s) are given by Eqs. (5) and (6) here >.
