This is because, unlike a treadmill in which your body absorbs the impact of walking and running, the Elliptical trainer if often described as walking in midair.
数值结果表明本文运用的方法对分析垂直于地面以及有耗或无耗介质半空间上的线天线是有效的。
Numerical results show that the method proposed in this paper is accurate and effective for the vertical thin-wire antennas above lossy or lossless dielectric half space.
而对于下半空间为带消散损耗的单负光疏介质时，仅TM波或TE波之一的古斯—汉森位移是负的。
However, as for the dissipative loss medium with only one of permittivity and permeability being negative, the TM or TE polarization incident wave has a negative Goos-Hanchen shift accordingly.
