Parallel wire, transmission lines Give examples The electromagnetic waves that are guided along or over conducting or dielectric surface are called guided waves.

EC Transmission Lines and Wave guides QUESTION PAPER

The operating wavelength is 90 m. The single stub matching system is based on the measurement of voltage minimum. Transmission line resonator can be built using distributed elements like sections of coaxial lines. A sc2305 stub also has a lower loss of energy due to radiation ,since the short.

A finite line is a line having a finite length on the line. An infinite line is a line in which the length of the transmission line is infinite. Transmizsion the field configuration, cut off frequency and velocity of propagation for TM waves in rectangular wave — guides? Will a TE11 mode be propagated?


Name the three basic configurations of coaxial resonators.

The root values for the TE modes are: The wave cannot be propagated. TE10 and TM10 Derive the equation for transfer impedance?

Explain double stub matching on a transmission line and derive the expression and the length of the stub used for matching on a line? The points along the line where magnitude of voltage or current is zero are called nodes while the the points along the lines where magnitude of voltage or current first maximum are called antinodes or loops. Mention the applications of wave guides Transmision wave guides are employed for transmission of energy at very high frequencies where the attenuation caused by wave guide is smaller.

Assume free space within the cavity. Measurements indicate that the standing wave aand are cm apart and that the last minimum is 35 cm from the load end of the line.

What is standing wave ratio? Derive the expression for attenuation of TE10 waves in rectangular wave guide? What are guided waves?

The ratio of the maximum to minimum magnitudes transmissoin voltage or current on a line having standing waves called standing waves ratio. The quarter wave line or transformer and the tapered line are some of the impendence matching devices. The range of values of standing wave ratio is theoretically 1 to infinity.

Calculate the cut-off wavelength, the guide wavelength and the characteristic wave impedance for the TE mode. This is called double stub matching. This is called impedance mismatch condition. The presence of electric field gives rise to a capacitance value and the presence of magnetic field gives rise to a inductance value and the finite e2c305 in the walls gives rise to loss along the walls giving rise to a resistance value.
