Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] like figure 1 An efficient adaptive frequency-sweeping broadband electromagnetic simulation method employs a rational function approximation to fit the measured or calculated frequency-domain response, which is achieved by a scaling procedure replacing a set of starting poles with a modified set of poles.
[0022] The inventive method comprises the following steps:
[0023] Step (1), the antenna is considered to be in the incident field (E inc ,H inc ) under the irradiation of an ideal conductor, the conductor is located in the electromagnetic parameters (ε (e) ,μ (e) ) in the medium space; the electric field and magnetic field in the outer region of the conductor are E e 、H e , the electric field and magnetic field inside the conductor are both 0; ε is the permittivity, μ is the magnetic permeability;
[0024] Step (2), according to the frequency range...
