a stratified medium model(transmisson line model)of the current distribution is presented for thin cylindrical antennas.
文中对细圆柱天线提出了电流分布的分层媒质模型(传输线模型)。
the optical recursive formula for stratified medium system becomes more general with the contribution of relative magnetic permeability to the complex refractive index.
文中考虑了材料的相对导磁系数对材料复数折射率的贡献,使分层介质系统的光学迭代法更具普遍性;
in this paper, the sound field of a more general directional radiator in a stratified medium is treated, and the concept of directivity is applied to calculation of the normal modes.
