An elliptically polarized wave may be resolved into two linearly polarized waves in phase quadrature, with their polarization planes at right angles to each other. Since the electric field can rotate clockwise or counterclockwise as it propagates, elliptically polarized waves exhibit chirality. Other forms of polarization, such as circular and linear polarization, can be considered to be special cases of elliptical polarization. ==Mathematical description of elliptical polarization== The classical sinusoidal plane wave solution of the electromagnetic wave equation for the electric and magnetic fields is (cgs units) :$\backslash mathbf\; (\; \backslash mathbf\; ,\; t\; )\; =\; \backslash mid\; \backslash mathbf\; \backslash mid\; \backslash mathrm\; \backslash left\; \backslash$ :$\backslash mathbf\; (\; \backslash mathbf\; ,\; t\; )\; =\; \backslash hat\; \backslash times\; \backslash mathbf\; (\; \backslash mathbf\; ,\; t\; )$ for the magnetic field, where k is the wavenumber, :$\backslash omega\_^\; =\; c\; k$ is the angular frequency of the wave propagating in the +z direction, and $c$ is the speed of light. Here $\backslash mid\; \backslash mathbf\; \backslash mid$ is the amplitude of the field and :$|\backslash psi\backslash rangle\; \backslash \; \backslash stackrel\backslash \; \backslash begin\; \backslash psi\_x\; \backslash \backslash \; \backslash psi\_y\; \backslash end\; =\; \backslash begin\; \backslash cos\backslash theta\; \backslash exp\; \backslash left\; (\; i\; \backslash alpha\_x\; \backslash right\; )\; \backslash \backslash \; \backslash sin\backslash theta\; \backslash exp\; \backslash left\; (\; i\; \backslash alpha\_y\; \backslash right\; )\; \backslash end$ is the normalized Jones vector. This is the most complete representation of polarized electromagnetic radiation and corresponds in general to elliptical polarization. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Elliptical polarization」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
