The coaxial lines are either opened or shunted at the end sections thus confining the electromagnetic energy within the section and acts as the resonant circuit having a natural resonant frequency.

Single stub matching is useful for a fixed frequency. The difficulties of the smith chart are i Single stub impedance matching requires the stub to be located at a definite point on the line. What is the dominant mode for the TM waves in the rectangular waveguide? Enter the email address you signed up with and we’ll email you a reset link. Define the line parameters?

## EC2305 Transmission Lines and Wave guides QUESTION PAPER

Why TEM mode is not possible in a rectangular waveguide? It has a electric field strength Ez in the direction of propagation and no component of magnetic field Hz in the same direction They are also called as primary ec235. Resonant frequency of microwave ce2305 is the frequency at which the energy in the resonator attains maximum value.

Derive the field configuration, cut off frequency and velocity of propagation for TM waves in rectangular wave — guides? When a signal having many frequency components are transmitted along the line, all the frequencies will not have same time of transmission, some frequencies being delayed more than others. Explain about different type of TL?

Free Particle Time Dependence. The TEM waves are waves in which both electric and magnetic fields are transverse entirely but have no components of Ez and Hz. It gives the manner in the wave is propagated along a line and specifies the variation of voltage and current in the line as a function of distance.

What is TE wave or H wave? TE10 and TM10 Derive the field strength or equation in cylindrical co — ordinates systems? What is cut off frequency? What are the possible modes for TM waves in a circular waveguide?

Derive the expression for the field strength for TE waves between parallel plates propagating in Z direction? TEM wave is a special type of TM wave in which an electric field E along the direction of propagation is also zero. Give the input impedance of open and short circuited lines. Transverse magnetic TM wave is a wave in which the magnetic field strength H is entirely transverse. Give reasons for preferring a short- circuited stub when compared to an open circuited stub.

A free-space medium is one in which there are no conduction currents and no charges. The ratio of the maximum to minimum magnitudes of current or voltage on a line having standing wave is called the standing-wave ratio S. Find the following for the TE1o made z 1 Cutoff frequency 2 Phase and group velocity.

Derive the expression for attenuation of TE10 waves in rectangular wave guide? Write down the expression for cut off frequency when the wave is propagated in between two parallel plates. The dominant transmmission of a circular resonator depends on the dimensions of the cavity.

Transmissiin the expression for the resonant frequency of the semi circular cavity resonator? The single stub matching system is based on the measurement of voltage minimum.

What is double stub matching? Define characteristic impedance in a waveguide The characteristic impedance Zo can be defined in terms of the voltage-current ratio or in terms of power transmitted for a given voltage or a given current.

For coaxial lines it is necessary to use a length of line in which a longitudinal slot, one half wavelength or more long has been cut.

The parameters of a transmission line are: What is the nature and value of Z0 for the dissipation less line? This is called impedance matching. What is an evanescent mode? The circular waveguides are ec23055 because of the following reasons: Derive the expression for the field strength for TM waves between Parallel plates propagating in Z direction?

What is a smooth line?
