The most common types of polarization include the linear (horizontal or vertical),circular (right hand polarization (RHCP)or the left hand polarization(LHCP)),Elliptical Right Hand and Elliptical Left Hand.An antenna erected vertically is said to be “vertically polarized” while an antenna erected horizontally is said(not so surprising) to be “horizontally polarized”.Other specialized antennas exist with “cross polarization”,having both vertical and horizontal components and we can have “circular polarization”.
答案
常见极化包括线形（水平或垂直）,圆形（右旋偏振RHCP或左旋偏振LHCP）,椭圆右旋或椭圆左旋.垂直竖立的天线被称为垂直极化,而水平放置的天线被称为水平极化（显而易见）.
其它专化天线存在正交偏振,同时具有垂直和水平分量,我们可得到圆偏振.
举一反三
已知函数f（x）=x，g（x）=alnx，a∈R．若曲线y=f（x）与曲线y=g（x）相交，且在交点处有相同的切线，求a的值和该切线方程．
