Is there a career mode on NBA 2k10 for the ps2?
Yes, if you're referring to my player mode.
Do the Shoshone still exist?
yes they do exist they live in calofornia
Did feudal mode of production existed in pre- colonial Africa?
Generally, by the beginning of the 19th century, most African societies had attained the communal mode of production. A few were under the slave mode of production, others were under the feudal mode of production, quite a few others were under a mixture of both the feudal and slave mode of productions. There fore, the modes of productions developed by African societies during pre-colonial era are, 1) Primitive communalism 2) Slavery 3) Feudal mode of production.
Did Guru Nanak really exist?
1.Did Jesus exist? Did Allah exist? Did Buddha exist? Do you exist? 2.There is an extremely low chance that Guru Nanak Dev Ji didn't exist; many records and stories of him were made. I think it's more of a question of did he know what god was really like (was he a holy man).
For how long did stagecoaches operate as a popular mode of transportation?
Stagecoaches operated as a popular mode of transportation for about 200 years, from the 17th to the 19th centuries.
Why TM01 mode does not exist in rectangular waveguide?
if any of the m or n in case of TM MODE becomes zero then all the field components vanishes. Hence the waveguide has no relevence with TM01, TM10 or TM00 modes. Therefore TM11 is the lowest order mode of all TMmn modes. For similer reasons TE00 mode can not propagate through the waveguide.
Why tm10 and tm01 does not exist in rectangular waveguide?
TM10 and TM01 modes do not exist in a rectangular waveguide because they do not satisfy the boundary conditions imposed by the waveguide's walls. Specifically, for a TM mode, there must be at least one electric field component that is zero at the conducting walls, and the TM10 and TM01 modes would require a non-zero electric field at one of the walls, violating this condition. Consequently, only certain transverse modes, such as TM11 and TM21, are supported in rectangular waveguides.
What is the dominant mode in rectangular waveguide?
Rectangular Waveguide - TE10; (TM11 in case of TM waves) Circular Waveguide - TE11;
What mode is less attenuation in circular waveguide?
TE10
Why tem mode is not support in rectangular waveguide?
The transverse electromagnetic (TEM) mode cannot propagate in a rectangular waveguide because it requires both electric and magnetic fields to have no component in the direction of propagation. In a rectangular waveguide, the boundary conditions imposed by the walls necessitate that at least one field component must be longitudinal (along the direction of propagation) for any mode to exist. Thus, only transverse modes (TE and TM) can propagate, as they support fields that are entirely transverse to the direction of wave travel.
What are the Differences between horn antenna and waveguide?
waveguide is a metal pipe that contains and guides microwaves from place to place in a microwave system (e.g. oscillators, amplifiers, mixers, modulators, filters, antennas)horn antenna has a waveguide connected at its focus, in transmit mode the waveguide feeds the horn which then emits a microwave beam, in receive mode the horn collects a microwave beam and concentrates it int the waveguide
What is the fundamental mode in circular waveguides?
The fundamental mode in circular waveguides is the TE11 mode, which is characterized by having one half-wave variation along the radius and one full-wave variation along the circumference of the waveguide. It is the lowest order mode that can propagate in a circular waveguide.
Why the te0 mode is the dominant mode in rectangular waveguide?
Because it has the lowest cut-off frequency (highest cut off wavelength) for a>b o
Why the te10 mode is the dominant mode in rectangular waveguide?
TE10 mode is the dominant mode with a>b, since it has the lowest attenuation of all modes. Either m or n can be zero, but not both.
Why rectangular wave guide is preferred over a square waveguide for usual microwave transmissions?
A square waveguide does not allow single mode operation as for example fc(TEmn)=fc(TEnm).
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.
Can a waveguide have more than one cut off frequency?
yes it can have coz fc= c/2[(m/a)2+(n/b)2]1/2 therefore for various modes(which decide m,n) nd dimensions(a,b) of waveguide it will have different cut off frequency. A normal waveguide is used in the octave frequency range where only the fundamental mode can propagate.
