摘　　要：用模式匹配法精确分析铁氧体片对称放置的脊形和槽形波导的准TEm0 模 ,并对几种特殊情形进行计算 ,结果与文献吻合 .进一步计算结果表明含铁氧体片的脊形波导具有宽频带特性 ,含铁氧体片的槽形波导具有较大相位移 .由于考虑了高次模 ,此方法较目前文献提及的方法更为精确 .A mode-matching method is used to accurately analyze the quasi-TEm0 mode in ferrite slabs symmetrically loaded ridged and grooved waveguides. Numerical results are identical to those in the references. Further computation indicates that the ferrite slabs loaded ridged waveguide has broadband frequency properties and the grooved waveguide has greater differential phase shift. With higher modes considered, this method is superior to those in literatures published in recent years.
