Two standard waveguides are given: WR3, with dimensions a = 0.86 mm and b = 0.43 mm, operatingat400GHz, andWR2300, with dimensions a = 0.5842 m and b = 0.2921 m operating at 600 MHz. Both waveguides are air filled (these two waveguides represent the smallest and largest standard waveguides).
(a) Find the TM11 cutoff frequencies of the two waveguides.
(b) Find the ratio between the total power carried by the two waveguides for a given electric field intensity E.
