Extracted text: (V.3) A common commercial size of rectangular hollow-conductor waveguide has (inner) dimensions a = 2.286 cm by b = 1.016 cm. (a) What is the single-mode bandwidth of this size waveguide frequency range (in gigahertz) within which the TE10 mode propagates but the next higher mode does not? [Most practical waveguide systems are operated under this single-mode condition.] that is, what is the (b) The maximum field strength that air can support without breakdown is about 50,000 V/cm (at standard atmospheric pressure). What is the maximum power that can be trans- mitted by this size waveguide at frequencies within the single-mode band?
