WebMay 4, 2011 · The continuous tuning range of fTHz Δ fTHz) is represented as: The value of m2 reaches 3 880 000 when the optical frequency of CWL2 is 194 THz (corresponding wavelength = 1550 nm) and frep2 is 50 MHz. For example, when Δ frep2 = 500 kHz, which is 1 % of frep2, Δ/Γ · Ηζ could reach about 2 THz from Equation [15.9]. Radio waves are emitted and received by antennas, which consist of conductors such as metal rod resonators. In artificial generation of radio waves, an electronic device called a transmitter generates an AC electric current which is applied to an antenna. The oscillating electrons in the antenna generate oscillating electric and magnetic fields that radiate away from the antenna as ra…
