phase constant การใช้

• In particular, the phase constant \ beta is not always equivalent to the wavenumber k.
• The phase constant is also an important concept in quantum mechanics because the momentum p of a quantum is directly proportional to it, i . e.
• In a cascaded topology, the propagation constant, attenuation constant and phase constant of individual sections may be simply added to find the total propagation constant etc.
• These quantities can also be known as the primary line constants to distinguish from the secondary line constants derived from them, these being the propagation constant, attenuation constant and phase constant.
• This requirement for proportionality to frequency is due to the relationship between the velocity, " v ", and phase constant, " ? " being given by,
• Because the symbols are smoothly shaped there is no need to keep the phase constant, which normally is the case when no ( e . g . square ) shaping is used.
• They say it's also called the phase constant or phase angle, but I don't know what it means physically and how to use it in an actual problem.
• These quantities can also be known as the primary line constants to distinguish from the secondary line constants derived from them, these being the characteristic impedance, the propagation constant, attenuation constant and phase constant.
• Where j is the imaginary unit, Z _ 0 is the characteristic impedance of the line, \ beta = 2 \ pi / \ lambda \, is the phase constant of the line, and l is the physical length of the line.
• The imaginary phase constant, " i? ", can be added directly to the attenuation constant, " ? ", to form a single complex number that can be handled in one mathematical operation provided they are to the same base.
• A very short transmission line, such as those being considered here, in many situations will have no appreciable loss along the length of the line and the propagation constant can be considered to be purely imaginary phase constant, " i? " and the impedance expression reduces to,
