Waveguides are structures designed to direct and control the propagation of electromagnetic waves from one point to another. They play a crucial role in various fields, including telecommunications, ...

This text provides an extensive introduction to the practical use of spectral methods in solving real engineering problems in open electromagnetic waveguide environments taken from the fields of ...

Sound spreads both forwards and backward in a space, meaning someone standing nearby can hear you as well as you can hear ...

The trick is to blow swirling air into the cavity at a specific speed and intensity, which allows the sound waves to ...

After years of research, scientists at ETH Zurich have developed a method to make sound waves travel in a single direction.

In our everyday world, waves are stubbornly democratic. Whether it’s the sound of a conversation, the glow of a lightbulb, or ...

Illustration of light passing through a two-dimensional waveguide array. Each waveguide is essentially a tube, which behaves like a wire for light, inscribed through high-quality glass using a ...

Infrared imaging technology is crucial for advancing our understanding of the world, from exploring biological specimens to ...

For that you need a special type of magnet – an electromagnet. Magnetism and electricity are very closely related. If a magnet is moving near to a wire it will generate an electric current and ...

The specimen raised eyebrows because it appeared to be capable of causing levitation. The official U.S. UFO analysis agency ...
