A microwave oven cooks food by irradiating the food with microwave power generated by a magnetron. Assuming the dielectric constant of a beef steak to be 40 with a loss tangent of 0.35 at an operating frequency 2.45 (GHz), calculate the average power per cubic meter. (Neglect skin effect, which will be discussed in Subsection 7-3.2.) ANS. 59.6 (kW/m³).
