Let us see what effects we would expect if we were to shine polarized light through a plate of a birefringent substance. If the polarization is parallel to the ...

The circular polarization state is a special polarization state of elliptical polarization state, which satisfies the following conditions: 1) The field must have two orthogonal polarized components (such as x-direction and y-direction). 2) The two components mist have the same magnitude (Ex = Ey), 3) The two components must have a time-phase difference of multiples of 90 degrees. Thus the field pattern can be written as:

the circular and elliptical polarization state can be formed by letting linear polarization wave pass through a quarter wave plate at the specific angle. And the linear polarization state can be formed by the linear polarization plate as well as the polarization rotator.

The above is a elliptical polarization which can be seen as the superposition of two circular polarization possessing different magnitude and direction. And the general elliptical polarization pattern is shown below:

Assume Ey in the mathematical expression for the electric field equals to zero, which gives the definition of electric field as:

Elliptical polarization

The cause of the light polarization is the vibration direction of the lighting material. The natural light comes from the molecular vibration of the nuclear fusion in Sun and this vibration is homogeneous on all directions. Thus the natural light does not have a specific polarization or can be defined as non-polarized EMW.

The circular polarization can be seen as the superposition of two linear polarization waves having the same magnitude, orthogonal polarization direction and pi/2 phase difference. The elliptical polarization wave can be seen as the superposition of two linear polarization waves having the different magnitude, orthogonal polarization state and the stable phase difference. Above all, the linear polarization state and circular polarization state are only the special states of elliptical polarization state.

Is that the Sioux City, Iowa crash? (sorry, I'm at work and can't watch the clip right now!) I remember seeing that on the news the night it happened. That pilot is—all pilots really are—remarkable in so many ways.

The elliptical polarization is the general definition of the EMW polarization state whose field pattern can be expressed after make the simple math transformation of Ex and Ey:

Yesyes, that's the one. (It was a little before I ever watched the news, so this is the first I've heard of it, but I'd imagine most people would find the expatiation interesting.)

"At the bottom of the craft is a flexible skirt which is controlled by releasing or pulling in a ring around the bottom of it. This directs the flow of air, and makes for a very simple and reportedly intuitive 360-degree steering process via a joystick. We're not sure how yaw will be controlled."- Entecho's Hoverpod: the 3-seat, skirt-steered, 75mph VTOL flying saucer, gizmag.com, 5 May 2009.

I just ran into this word in reference to flying, in this documentary: a pilot chooses to board a plane that meets the one-in-a-billion chance of total hydrolic failure, and manages to land it, against odds that no one on board would survive. The guy's very well-spoken, and goes into a good amount of detail — it's an unbelievable story, and a comforting reminder of just how capable these people are.

The polarization of electromagnetic wave (EMW) is the basic property of the EMW, which is widely used and controlled in Laser3,4, interferometer5,6 and photography7. The sketch for the linear polarization (red curves) of EMW is shown in Fig.1 below.

The electromagnetic waves such as visible light and microwaves consist of orthogonal electric and magnetic field both orthogonal to the propagation direction of the wave. The polarization of the electromagnetic wave is meant to describe the magnitude and the direction of the electric field of the wave. Specifically, the polarization of a radiated wave is defined as "that property of a radiated electromagnetic wave describing the time-varying direction and relative magnitude of the electric field vector; the trace and magnitude of the electric field vector are observed in the direction of light propagation"1,2,

Generally, with x-direction oscillation and y-direction oscillation share the same phase, the linear polarization field pattern can be express as:

based on the Maxwell equations9 for EMW, the electric field can be split into orthogonal x-component Exand y-component Ey10 :

the left circular polarization (counterclockwise) is achieved when number n equals to (4m-1) (m is integer) and the right circular polarization (clockwise) is achieved when number n equals to (4m+1).

The electric field on certain propagation position will oscillate only on the x-axis with the angular frequency of omega, which is shown as below:

Circular polarization

Thus, the similar polarization of electric field on only a specific straight direction is defined as linear polarization. On the other hand, Assume Ey equals to zero, which gives the electric field as:

where Ex is the magnitude of the electric field in x-direction, Ey is the magnitude of the electric field in x-direction, Phix is the phase of the electric field in x-direction, Phiy is the phase of the electric field in y-direction and omega is the frequency of the EMW. The three major polarization state are defined based on the differences in phase and magnitude of x-direction and y-direction EMW.
