Plane polarized electromagnetic wave

We shall now simplify the problem by considering the case where E and Ey = 0, with E as the only effective component of the electric field. E, moreover, is to be uniform over the whole XT-plane (plane and plane-polarized electromagnetic wave). [Pg.219]

Figure 1.17 illustrates the classical case of a plane polarized electromagnetic wave whose electric field varies in the jc direction. Let this wave approach a rotating molecule with a permanent dipole moment /a (a nonzero dipole moment at equilibrium). For simplicity allow the x direction to lie in the plane defined by the rotating dipole moment. If the angle the dipole moment makes with the x direction is 6, then the component of the dipole moment in the x direction is... [Pg.37]

Exercise 7.1 Show that the plane-polarized electromagnetic wave in Eq. (7.1) is a solution to Maxwell s equation for the vector potential in vacuum Eq. (2.129). [Pg.154]

A plane polarized electromagnetic wave traveling in the y direction can have an electric field that oscillates in the yz plane and a magnetic field that oscillates in the xy plane. In a medium with zero electrical conductivity (a perfect insulator or a vacuum), the following equations for such a wave follow from Maxwell s equations. ... [Pg.1275]

At the surface of metals, the surface plasmon-polaritons, also called "surface plasmons," are not the same as the "bulk" plasmons these surface plasmons are affected (i.e., shifted slightly in energy) by monolayer adsorbates thus Surface Plasmon Resonance (SPR) spectroscopy yields information about the nature of the binding of the adsorbates onto a metal surface. The surface plasmons are excited by a p-polarized electromagnetic wave (polarized in the plane of the film) that crosses a glass medium (1), such as a prism, and is partially reflected by a metallic film (2) and back into the glass medium the dispersion relation is... [Pg.450]

Plane-polarized electromagnetic radiation is produced by certain radiant energy sources. For example, the radio waves emanating from an antenna and the microwaves produced by a klystron tube are both plane polarized. Visible and ultraviolet radiation from relaxation of a single excited atom or molecule is also polarized, but the beam from such a source has no net... [Pg.608]

Solving Maxwell s equations [see Exercise 7.1] for the vector potential of a plane or linear polarized electromagnetic wave oscillating with angular frequency w gives... [Pg.153]

Plane-polarized light (Section 9.3) Ordinary light that has its electromagnetic waves oscillating in a single plane rather than in random planes. The plane of polarization is rotated when the light is passed through a solution of a chiral substance. [Pg.1247]

If the foregoing created the impression that the electric and magnetic vectors of a propagating electromagnetic field are confined to vibrate in fixed planes, that was unintentional. A field like that would be plane polarized and to create that requires a special device known as a polarizer. Ordinary unpolarized light consists of an array of plane waves that are randomly oriented with respect to a plane perpendicular to the directions of propagation. [Pg.138]

Polar Molecule a molecule where the centers of positive and negative charge differ, creating a permanent dipole moment Polarizability ability of an electron cloud in a neutral atom to be distorted Polarized Light light in which the electromagnetic wave vibrates in only one plane Polyatomic Ion an ion consisting of more than one atom... [Pg.346]

In addition to irradiance and frequency, a monochromatic (i.e., time-harmonic) electromagnetic wave has a property called its state of polarization, a property that was briefly touched on in Section 2.7, where it was shown that the reflectance of obliquely incident light depends on the polarization of the electric field. In fact, polarization would be an uninteresting property were it not for the fact that two waves with identical frequency and irradiance, but different polarization, can behave quite differently. Before we leave the subject of plane waves it is desirable to present polarization in a systematic way, which will prove to be useful when we discuss the polarization of scattered light. [Pg.44]

The nonzero angular momentum which does not exist for circularly and plane polarized conventional electromagnetic waves... [Pg.49]

It is instructive to pursue the interpretation of the calcite rhomb experiment beyond the simple Huyghenian construction to learn something about the polarization of the transmitted light. The electromagnetic theory of light requires that the electric vector shall be contained in the plane of the wave front. The ordinary disturbances vibrate perpendicular to a principal section. Also the extraordinary disturbance must vibrate in the principal section plane. [Pg.79]

In an anisotropic dielectric the phase velocity of an electromagnetic wave generally depends on both its polarization and its direction of propagation. The solutions to Maxwell s electromagnetic wave equations for a plane wave show that it is the vectors D and H which are perpendicular to the wave propagation direction and that, in general, the direction of energy flow does not coincide with this. [Pg.438]

Plane-polarized light (Section 7.4) A light beam in which the electromagnetic field of all the waves oscillate in a single plane. [Pg.1276]
