broadwall meaning in English

长壁开采

Abstract : according to the continuative condition of the tangential fields on the slot aperture which is the inclined narrow - slot on the broadwall of a sectoral waveguide , the moment method is used to calculate the magnetic current coefficient and distribution . then the scattering field , the scattering parameter and the equivalent impedance are obtained . leting only the te11 dominant mode propagates in the waveguide , the scattering parameters and the normalized equivalent series impedance in the x - band are computed . the basis disigned the slot antenna and the slot array is offered
