Analysing the propagation of EM wave for the circular tunnels and tunnels with a contained axial conductor, the formulas of attenuation and the mode equations are given and they are solved by the Muller s way.
對空圓形隧道及隧道中含有縱向?qū)w的電磁波傳輸特性進(jìn)行分析,給出了相應(yīng)的衰減率計算公式及波模方程,并且采用Muller法對其進(jìn)行求解。
From the equations of normal modes of crystals, the direction of the optical axis in biaxial crystals is found and the corresponding vectors of electric field and electric displacement are derived when lights travel in the direction of the optical axis.
從晶體的簡正模方程出發(fā)，求得在雙軸晶體中光軸方向，及當(dāng)光線沿光軸方向行進(jìn)時所對應(yīng)的電場矢量和電位移矢量，并通過幾何作圖，證明所有折射光線在晶體內(nèi)均在同一錐面上。
