ECE :: Microwave Communication
-
Assertion (A): In rectangular waveguide TE01 mode is just TE10 mode rotated by 90°.
Reason (R): When a rectangular waveguide is rotated by 90°, the broad and narrow dimensions get interchanged.
-
Consider the following statements about a magic tee
- The collinear arms are isolated from each other.
- On of the collinear arms is isolated from E arm.
- On of the collinear arms is isolated from H arm.
- E and H arms are isolated from each other.
-
Assertion (A): Hollow waveguides are frequently used as transmission lines at microwave frequencies.
Reason (R): Waveguide has high power handling capacity, low loss and simple structure.
