  2. Transverse wave - Wikipedia

    en.wikipedia.org/wiki/Transverse_wave

    Mathematically, the simplest kind of transverse wave is a plane linearly polarized sinusoidal one. "Plane" here means that the direction of propagation is unchanging and the same over the whole medium; "linearly polarized" means that the direction of displacement too is unchanging and the same over the whole medium; and the magnitude of the displacement is a sinusoidal function only of time ...

  3. Transverse mode - Wikipedia

    en.wikipedia.org/wiki/Transverse_mode

    A transverse mode of electromagnetic radiation is a particular electromagnetic field pattern of the radiation in the plane perpendicular (i.e., transverse) to the radiation's propagation direction. Transverse modes occur in radio waves and microwaves confined to a waveguide , and also in light waves in an optical fiber and in a laser 's optical ...

  4. Polarization (waves) - Wikipedia

    en.wikipedia.org/wiki/Polarization_(waves)

    Electromagnetic waves (such as light), traveling in free space or another homogeneous isotropic non-attenuating medium, are properly described as transverse waves, meaning that a plane wave's electric field vector E and magnetic field H are each in some direction perpendicular to (or "transverse" to) the direction of wave propagation; E and H ...

  5. Electromagnetic radiation - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_radiation

    Representation of the electric field vector of a wave of circularly polarized electromagnetic radiation. In homogeneous, isotropic media, electromagnetic radiation is a transverse wave, [25] meaning that its oscillations are perpendicular to the direction of

  6. Mode conversion - Wikipedia

    en.wikipedia.org/wiki/Mode_conversion

    Mode conversion occurs when a wave encounters an interface between materials of different impedances and the incident angle is not normal to the interface. [1] Thus, for example, if a longitudinal wave from a fluid (e.g., water or air) strikes a solid (e.g., steel plate), it is usually refracted and reflected as a function of the angle of incidence, but if some of the energy causes particle ...

  7. Sinusoidal plane-wave solutions of the electromagnetic wave ...

    en.wikipedia.org/wiki/Sinusoidal_plane-wave...

    Electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields. This diagram shows a plane linearly polarized wave propagating from right to left. The magnetic field (labeled M) is in a horizontal plane, and the electric field (labeled E) is in a vertical plane.

  8. Gaussian beam - Wikipedia

    en.wikipedia.org/wiki/Gaussian_beam

    The equations below assume a beam with a circular cross-section at all values of z; this can be seen by noting that a single transverse dimension, r, appears.Beams with elliptical cross-sections, or with waists at different positions in z for the two transverse dimensions (astigmatic beams) can also be described as Gaussian beams, but with distinct values of w 0 and of the z = 0 location for ...

  9. Wave - Wikipedia

    en.wikipedia.org/wiki/Wave

    A plane wave is classified as a transverse wave if the field disturbance at each point is described by a vector perpendicular to the direction of propagation (also the direction of energy transfer); or longitudinal wave if those vectors are aligned with the propagation direction. Mechanical waves include both transverse and longitudinal waves ...
