Generating Electromagnetic Radiations

4.2K
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...

Prismatic Beams: Problem Solving

208
In the design of a supported timber beam subjected to a distributed load, both the beam's physical dimensions and the timber's characteristics, such as its grade and species, are critical. These factors determine the allowable stress values, which are crucial for calculating the necessary beam depth to ensure structural integrity and safety.
The design begins with analyzing the beam as a free body to identify moments and force balances, thereby determining support reactions. Next, the...

Beams with Symmetric Loadings

The moment-area method is an analytical tool used in structural engineering to determine the slope and deflection of beams under various loads. Consider a cantilever with a concentrated load and moment at the free end. The first step is constructing a free-body diagram to calculate the reactions at the fixed end. Next, the bending moment diagram is plotted to visualize how the bending moment varies along the beam's length, focusing on points where the bending moment equals zero.
The M/EI...

    Area of Science:

    • Optics and Photonics
    • Quantum Optics
    • Beam Propagation

    Background:

    • Airy beams exhibit non-diffracting and self-healing properties.
    • Partially coherent light sources present challenges in beam shaping and propagation control.

    Purpose of the Study:

    • To introduce and characterize a novel class of partially coherent light sources generating Airy-type beams.

    • Experimental demonstration of beam propagation and robustness using a hard aperture.

    Main Results:

    • The generated Airy-type beams exhibit strong preservation of their pattern during propagation.
    • The Airy beam pattern demonstrates remarkable robustness against partial blockage of the source.
    • Coherence-induced Airy beams can be effectively reconstructed after encountering an obstruction.

    Conclusions:

    • Partially coherent light sources with Airy-type correlations offer robust Airy beam generation.
    • The demonstrated robustness opens possibilities for applications in complex media, such as free-space optical communication.
