Wavelength is defined, and students use the wave equation to solve problems. Wavelength is defined, and students use the wave equation to solve problems. Reflection is described at boundaries of ...

The interface between two facets of an artificial material known as a “Weyl phononic crystal” can not only negatively refract an airborne sound wave, it does so without reflecting it at all. This ...

Introduction to electromagnetic waves in electrical engineering. Topics include: concepts of transmission lines, electrostatics and magnetostatics; Maxwell's equations for time-varying fields; ...

NEW YORK, March 13, 2023 — When we look in a mirror, we are used to seeing our faces looking back at us. The reflected images are produced by electromagnetic light waves bouncing off of the mirrored ...

Scientists are engineering electromagnetic waves to retrace their temporal paths, a breakthrough in wave physics. This 'time reversal' doesn't involve historical travel but reverses a wave's sequence, ...
