The fоllоwing infоrmаtion pertаins to Questions 10 through 12. Filters of very high quаlity can be constructed using waveguide cavities. In this problem we consider a cavity constructed using WR-229 rectangular waveguide (with cross-section dimensions a = 58.166 mm and b = 29.083 mm). Consider a cavity formed from this waveguide. Take c = 3 x 108 (m/s) and η0 = 120 π (ohms). Assume that the cavity is filled with air and that . What is the lowest order mode (having lowest resonant frequency) of this waveguide cavity?
