Propagation of Waves01:07

Propagation of Waves

3.1K
When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...

Interference and Diffraction02:18

Interference and Diffraction

53.1K
Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Standing Waves in a Cavity01:28

Standing Waves in a Cavity

1.6K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

Modes of Standing Waves: II01:04

Modes of Standing Waves: II

1.9K
The starting point for expressing the modes of standing waves is understanding the boundary conditions that the waves must follow. The boundary conditions are derived from the physical understanding of how the standing waves are sustained, that is, how the vibrating particles of the medium behave at the boundaries imposed on them.
For a tube open at one end and closed at the other filled with air, the modes are such that there is always an antinode at the open end and a node at the closed end....

Plane Electromagnetic Waves I

5.2K
The existence of combined electric and magnetic fields that propagate through space as electromagnetic (EM) waves is the most significant prediction of Maxwell's equations. As Maxwell's equations hold in free space, the predicted electromagnetic waves do not require a medium for their propagation. An EM wave comprises an electric field, defined as the force per charge on a stationary charge, and a magnetic field, which is the force per charge on a moving charge.
The EM field is assumed to be a...

    Area of Science:

    • Optics and Photonics
    • Terahertz Science and Technology
    • Waveguide Physics

    Background:

    • Extraordinary optical transmission (EOT) is a phenomenon observed in periodic arrays of subwavelength apertures.
    • Conventional EOT models often rely on surface plasmon excitation, which may not fully explain transmission characteristics in all configurations.
    • Terahertz (THz) frequency range offers unique opportunities for studying wave-matter interactions due to specific material properties and source/detector availability.

    Purpose of the Study:

    • To investigate the influence of different input spatial modes on the EOT effect within a terahertz parallel-plate waveguide (PPWG).
    • To compare the predictive power of conventional EOT descriptions with an alternative impedance matching formalism.
    • To understand how waveguide mode characteristics affect spectral resonances in subwavelength hole arrays.

    Main Methods:

    • Fabrication of a metal screen with a 1D array of subwavelength holes.
    • Integration of the screen within a THz parallel-plate waveguide (PPWG).
    • Measurement and analysis of transmission spectra for various input waveguide modes (TEM and non-TEM).
    • Application of an impedance matching formalism for theoretical prediction.

    Main Results:

    • The transmitted spectrum of the EOT effect is strongly dependent on the input spatial mode.
    • Surface plasmon excitation models were found to be insufficient for predicting spectral resonances in all tested cases.
    • The impedance matching formalism accurately predicted spectral resonances for both transverse electromagnetic (TEM) and non-TEM input modes.

    Conclusions:

    • Input spatial mode is a critical factor governing EOT in THz PPWGs.
    • Impedance matching provides a more robust theoretical framework than surface plasmon excitation for describing EOT resonances in this configuration.
    • This work offers enhanced understanding and predictive capability for designing optical devices utilizing EOT in waveguide structures.
