A waveguide is a structure which guides waves, such as electromagnetic waves or sound waves. There are different types of waveguide for each type of wave. The original and most common meaning is a hollow conductive metal pipe used to carry high frequency radio waves, particularly microwaves.
Waveguides differ in their geometry which can confine energy in one dimension such as in slab waveguides or two dimensions as in fiber or channel waveguides. In addition, different waveguides are needed to guide different frequencies: an optical fiber guiding light (high frequency) will not guide microwaves (which have a much lower frequency). As a rule of thumb, the width of a waveguide needs to be of the same order of magnitude as the wavelength of the guided wave.
What else can I help you with?
What is circular waveguide?
It is a waveguide that is circular. Circular waveguides have modes that are described in terms of Bessel functions instead of the sines/cosines used for rectangular waveguides. The disadvantage is that the two lowest modes have cutoff frequencies spaced by less than an octave. Circular waveguides are used for rotating joints, for example in radar. The H01 mode in circular waveguide was used as a low-loss mode for transmitting signals over distance, but this technique has been replaced by fibre-optic cables.
What are power system transients?
Power system transients are voltage or current spikes, sudden and brief increases or decreases in the supplied power. These can be harmful for some types of electronic devices, and can be seen by a brief flicker of either dimmer or brighter light from light bulbs.
What are the electronics and communication engineering applications of vector calculus?
The theory of radio waves and waveguides is explained in terms of equations in the form of vector calculus. Examples are Maxwell's equations.
What is a brief explanation of what subsystem means?
A subsystem is a system inside another system. An example of this is an engine inside a car.If we consider the car as a whole as a system, then the engine is a system within that system, thus a subsystem.The car can then be part of a larger system, like a traffice jam, or the universe.

Why waveguides are used instead of antennas?
waveguides are used instead of coax because at the high microwave frequencies coax would radiate the signal right through its shield. waveguides do not replace antennas.

What is an explanation of optical communication through waveguides?
Optical communication through waveguides involves the transmission of light signals along a structured medium, typically made from glass or plastic. These waveguides confine light within their boundaries using total internal reflection, allowing for efficient signal propagation over long distances with minimal loss. This technology is fundamental in fiber optic communication systems, enabling high-speed data transfer for telecommunications and internet services. Waveguides can vary in design, including fibers and integrated photonic circuits, each tailored for specific applications.
