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, ...

Electromagnetic polarization techniques in waveguide systems encompass the control, conversion and separation of orthogonal field components within metallic or dielectric conduits. Such control ...

A new study by researchers at Lanzhou University and Hubei University proposes a quantum battery (QB) charging scheme based on a rectangular hollow metal waveguide. This approach allows them to ...

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concepts of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.

(Nanowerk Spotlight) The concepts of metamaterials and metasurfaces have spawned massive novel applications in free-space optics. However, recent research also indicates that they possess prominent ...

In our discussion of transmission lines, we pointed out that the resistance of a conductor increases with an increase in the signal frequency, leading to an increase in power loss along the line. This ...

Waveguide-to-coaxial adapters are RF adapters used to connect waveguide devices to coaxial components. What are Coaxial Cables and Waveguides? Coaxial cables are electrical cables with three or more ...

What are modal effects? Integrated photonics—the devices and the materials used to make them happen. One of the key planar-waveguide configurations: the ring resonator. The roots of waveguide optics ...

There are different antenna options for transmitting and receiving a radar signal. This blog will focus on how to connect a monolithic microwave integrated circuit (MMIC) radar transceiver to the ...

Pilots flying the Embraer Legacy 450 and 500 business jets are among the first to be using an augmented reality-based technology within their head-up displays (HUDs). The technology, waveguide optics, ...
