The process of cooking by microwave was patented in 1946, and by the 1970s microwave ovens had become standard household items.

CHAPTER 2 33 Chapter 2 Sections 2-1 to 2-4: Transmission-Line Model Problem 2.1 A transmission line of length l connects a load to a sinusoidal voltage source with an oscillation frequency f . Assuming the velocity of wave propagation on the line is c , for which of the following situations is it reasonable to ignore the presence of the transmission line in the solution of the circuit: (a) l 20 cm, f 20 kHz, (b) l 50 km, f 60 Hz, (c) l 20 cm, f 600 MHz, (d) l 1 mm, f 100 GHz. Solution: A transmission line is negligible when l λ 0 01. (a) l λ l f u p 20 10 2 m 20 10 3 Hz 3 10 8 m/s 1 33 10 5 (negligible).
