Standing Electromagnetic Waves01:15

Standing Electromagnetic Waves

Electromagnetic waves can be reflected; the surface of a conductor or a dielectric can act as a reflector. As electric and magnetic fields obey the superposition principle, so do electromagnetic waves. The superposition of an incident wave and a reflected electromagnetic wave produces a standing wave analogous to the standing waves created on a stretched string.
Suppose a sheet of a perfect conductor is placed in the yz-plane, and a linearly polarized electromagnetic wave traveling in the...
Generating Electromagnetic Radiations01:10

Generating Electromagnetic Radiations

The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in the...
Electromagnetic Fields01:30

Electromagnetic Fields

Electric fields generated by static charges, often referred to as electrostatic fields, are characteristically different from electric fields created by time-varying magnetic fields. While the former is a conservative field, implying that no net work is done on a test charge if it goes around in a complete loop in the field, the latter is, by definition, not a conservative field; net work is done, and it is proportional to the rate of change of magnetic flux.
However, the observation of Gauss's...
Plane Electromagnetic Waves I01:30

Plane Electromagnetic Waves I

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...
Standing Waves in a Cavity01:28

Standing Waves in a Cavity

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:
Magnetic Field Due To A Thin Straight Wire01:27

Magnetic Field Due To A Thin Straight Wire

Consider an infinitely long straight wire carrying a current I. The magnetic field at point P at a distance a from the origin can be calculated using the Biot-Savart law.

Area of Science:

  • Physics
  • Materials Science
  • Electromagnetism

Background:

  • Traditional electromagnetic meta-materials often rely on embedded or deposited metallic structures.
  • This embedding can influence or limit the material's electromagnetic response, tying it to substrate properties.

Purpose of the Study:

  • To experimentally demonstrate a novel electromagnetic meta-material (EM(3)) with free-space suspended metallic structures.
  • To achieve a meta-material whose electromagnetic response is governed purely by its geometrical parameters and constituent metal properties.

Main Methods:

  • Fabrication of micromanufactured S-shaped gold strings.
  • Suspension of these strings in free space using window-frames to create a bi-layer chip.
  • Characterization using Fourier transform interferometry and numerical simulation.

Main Results:

  • Demonstration of a 2D left-handed pass-band in the terahertz (THz) range (1.4–2.2 THz).
  • Observation of two distinct magnetic resonant loops within the pass-band.
  • Achieved a useful chip area of 56 mm(2).

Conclusions:

  • The developed meta-material design, free from substrates, allows for response dictated solely by geometry and metal properties.
  • This work represents a significant step towards realizing electromagnetic meta-materials that align with the conventional understanding of materials.
  • The findings open avenues for designing tunable and reconfigurable meta-materials with precise electromagnetic characteristics.
