EC2305 Transmission Lines and Wave guides QUESTION PAPER

This is called impedance mismatch condition. Thus the cavity resonator can be represented by a equivalent LCR circuit and have a natural resonant frequency Equalizers are networks whose frequency and phase characteristics are adjusted to be inverse to those of the lines, which result in amd uniform frequency response over the desired frequency band, and hence the phase is equal for all the frequencies.

Give the input impendence of eighth wave line terminated in a pure resistance Rr. What is the application of lins quarter wave matching section? If the load impedance is not equal to the llines impedance, then all the power that are transmitted from the source will not reach the load end and hence some power is wasted. Explain about characteristic impedance in rectangular wave guide?

State the relation between standing wave ratio and reflection coefficient. What are degenerate modes in a rectangular waveguide? Loading is the process of increasing the inductance value by placing trxnsmission inductors at specific intervals along the line, which avoids the distortion State the relation between standing were ratio S and reflection co-efficient k.

Explain why TM01 and TM10 modes in a rectangular waveguide do not exist. What is meant by cavity resonator? Give the equation for the radius of a circle diagram. What is called standing wave ratio?

Derive the expression for the field strength for TM waves between Parallel plates propagating in Z direction? The input impedance of open aned short circuited lines are given by, Derive the TM wave components in circular wave guides using Bessel functions? For TM modes in rectangular waveguides, neither m or n can be zero because all the field equations vanish i. What is delay distortion? Since the root value of TE11 is lower than TM01TE11 is the dominant or the lowest order mode for a circular waveguide.

The parameters of linss transmission line transmissiom What are the types of line distortions? A finite line, which is terminated in its characteristic impedance, is termed as infinite line.

Derive the expression for input impedance of lossless line? Rectangular or circular cavities can be used as microwave resonators because they have natural resonant frequency and behave like a LCR circuit. What is Impedance matching? It is waveguidse process of using sections of continuously loaded cables separated by sections of unloaded cables which increases the inductance value Give examples The electromagnetic waves that are guided along or over conducting or dielectric surface are called guided waves.

Why is TM01 mode preferred to the TE01 mode in a circular waveguide? An eighth wave line is used to transform any resistance to an waveguidew with a magnitude equal to Roof the line or to obtain a magnitude match between a resistance of any value amd a source of Ro internal resistance. The performance parameters of microwave resonator are:
