Based on the method of linear polarization, AC impedance and time potential, it is studied that the properties of seawater corrosion resistance of rebar in normal concrete and fly ash concrete.
Compare to the normal rectangular waveguide, ridge waveguide has the character of broader bandwidth, smaller dimension, lower equivalent characteristic impedance, etc.
与普通矩形波导相比，脊波导具有工作频带宽、尺寸小、等效特性阻抗低等特点。
