Propagation Speed of Electromagnetic Waves01:30

Propagation Speed of Electromagnetic Waves

Electromagnetic waves are consistent with Ampere's law. Assuming there is no conduction current Ampere's law is given as:
Speed of a Transverse Wave01:13

Speed of a Transverse Wave

The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound. The speed of the waves on the strings and the wavelength determine the frequency of the sound produced. The strings on a guitar have different thicknesses but may be made of similar material. They have different linear densities, and the linear density is defined as the mass per length.
One of the key properties of any wave is the wave speed. Light...

Design Example

The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...
Properties of Fourier Transform II01:24

Properties of Fourier Transform II

The Fourier Transform (FT) is an essential mathematical tool in signal processing, transforming a time-domain signal into its frequency-domain representation. This transformation elucidates the relationship between time and frequency domains through several properties, each revealing unique aspects of signal behavior.
The Frequency Shifting property of Fourier Transforms highlights that a shift in the frequency domain corresponds to a phase shift in the time domain. Mathematically, if x(t) has...

Electromagnetic Waves

James Clerk Maxwell formulated a single theory combining all the electric and magnetic effects scientists knew during that time, calling the phenomena his theory predicted “Electromagnetic waves”. He brought together all the work that had been done by brilliant physicists such as Oersted, Coulomb, Gauss, and Faraday and added his own insights to develop the overarching theory of electromagnetism. Maxwell’s equations, combined with the Lorentz force law, encompass all the laws of electricity and...
Time and frequency -Domain Interpretation of Phase-lag Control01:21

Time and frequency -Domain Interpretation of Phase-lag Control

Phase-lag controllers are widely used in control systems to improve stability and reduce steady-state errors. A dimmer switch controlling the brightness of a light bulb serves as a practical example of phase-lag control, gradually adjusting the bulb's brightness. Mathematically, phase-lag control or low-pass filtering is represented when the factor 'a' is less than 1.
Phase-lag controllers do not place a pole at zero, but instead influence the steady-state error by amplifying any finite,...

Area of Science:

  • Optics and Photonics
  • Metamaterials
  • Information Security

Background:

  • Metamaterials enable exotic properties like negative refractive index, leading to research in invisibility cloaks.
  • Temporal cloaking, hiding events in time, has been demonstrated but limited to brief, isolated events.
  • Previous methods had low cloaking efficiency (10^-4%) and repetition rates (41 kHz), unsuitable for optical communications.

Purpose of the Study:

  • To demonstrate a novel temporal cloaking technique for practical applications.
  • To achieve high cloaking efficiency at telecommunication data rates.
  • To enable secure optical data transmission.

Main Methods:

  • Exploiting the temporal Talbot effect for self-imaging.
  • Developing a temporal cloaking technique operating at telecommunication data rates.
  • Concealing pseudorandom digital data streams.

Main Results:

  • Achieved cloaking of 46% of the entire time axis.
  • Demonstrated data concealment at a rate of 12.7 gigabits per second.
  • Successfully hid optical data from a receiver.

Conclusions:

  • The demonstrated temporal cloaking technique operates at practical data rates.
  • This method has immediate ramifications for secure communications.
  • Temporal cloaking is now a viable technology for real-world applications.
