A waveguide is a structure that guides waves, such as electromagnetic waves or sound, with minimal loss of energy by restricting the transmission of energy to one direction. Without the physical constraint of a waveguide, wave intensities decrease according to the inverse square law as they expand into three dimensional space.

What is wr-821?
WR-821 is a type of waveguide used in microwave engineering, specifically designed for frequencies within the 18 to 26.5 GHz range. It is often used in applications such as radar, satellite communications, and other high-frequency transmission systems. The designation "WR" stands for "waveguide rectangular," and the number indicates its specific dimensions and frequency range. These waveguides facilitate the efficient transmission of microwave signals with minimal losses.
Does white rice have starch?
The main source of its energy is the starch. Rice is a high energy source. It is high in carbohydrates.
Why transmission is done on 11kv and 33kv?
High voltage reduces the amount of energy wasted in transmission lines.
What is the immediate source of energy to reform ATP into ADP molecules?
The immediate source of energy to reform ATP into ADP molecules is the breaking of high-energy phosphate bonds within the cell. This process releases energy that can be used to drive the conversion of ADP back into ATP through the process of phosphorylation. Phosphorylation involves the addition of a phosphate group to ADP, which requires energy input to form the high-energy phosphate bonds in ATP.
What do you call electrical energy that can be sent long distances?
High voltage transmission.
When is it advantageous to use a circular waveguide?
Circular waveguides are advantageous when working with high-frequency electromagnetic waves, such as in microwave and millimeter-wave applications. They are more efficient in guiding and transmitting these high-frequency signals due to lower losses and higher power-handling capabilities compared to other transmission mediums like coaxial cables. Additionally, circular waveguides are often used in radar systems and satellite communication due to their ability to pass through various bends and curves with minimal signal loss.
Does an air conditoner use mechanical energy?
Yes, it uses mechanical energy to convert the gases to high pressures in the compressor. The compressor gets energy from electrical source, then that source is converted to mechanical energy, then to hydraulic energy.
Is cracked corn a energy food source for livestock?
Cracked corn is indeed an energy feed source for livestock. Corn is a high-energy feedstuff no matter how it's processed, and should be treated as such.
What is the energy source for transcription?
The energy for transcription comes from the hydrolysis of high-energy phosphate bonds in the form of nucleoside triphosphates, primarily ATP and GTP, which are used to drive the process of RNA synthesis.
What cause high reflected power in transmission line?
Poorly matched terminating impedances will result in high reflection. Tuning networks on both ends are used to tune the source and load to the same impedance as the transmission line.
Why is ATP considered a good source of energy?
ATP is considered a good source of energy because it is a high-energy molecule that can quickly release energy when needed for cellular processes, such as muscle contraction or nerve signaling. This rapid energy release makes ATP an efficient and readily available source of energy for various biological functions in the body.
What is the dissimilarity between waveguide and transmission line?
i am kuldeep b. shukla.this is my ans: Comparison of Waveguide and Transmission Line Characteristics Transmission line • Two or more conductors s eparated by some insulating medium (two-wi r e, coaxi al , microstrip, etc.). • Normal ope rating mode is the TEM or quasi-TEM mode (can support TE and TM modes but the s e mode s a r e ty pic a l l y undesirable). • No cutoff frequency for the TEM mode. Transmission lines can transmit signals from DC up to high frequency. • Significant signal attenuation at h i g h f re q u e n cies d u e t o conductor and dielectric losses. • Small cross-section transmission lines (like coaxial cables) can only transmit low power levels due to the relatively high fields concentrated at specific locations within the device (field levels are limited by dielectric breakdown). • Large cross-section transmission lines (like power transmission lines) can transmit high power levels. Waveguide 1. Metal waveguides are typically one enclosed conductor filled with an insulating medium (rectangular, circular) while a dielectric waveguide consists of multiple dielectrics. 2.Ope rating modes are TE or TM modes (cannot support a TEM mode). 3. Must operate the waveguide at a frequency above the respective TE or TM mode cutoff frequency for that mode to propagate. 4. Lowe r signal attenuation a t high frequencies than transmission lines. 5. Metal waveguides can transmit high powe r levels. The fields of the propagating wave are spread more uniformly over a larger cross-se ctional area than the small cross-section transmission line. 6. L arg e cro ss-sectio n (lo w f r e quency) wavegui de s a r e impractical due to large size and high cost.
