Module 8.5: Microwave Cooking

Given: A 2.5-cm thick steak of beef placed in a 2.45-GHz microwave oven. The purpose of this module is to estimate how much microwave energy is absorbed by the steak and converted into heat.

 

Q1.	Determine the value of |1|, the reflection coefficient at the air-meat boundary.
	|1|=
Q2.	With P1 = 10 W, what is the value of P2?
	P2=	W
Q3.	Determine the value of the attenuation coefficient in the meat medium.
	=	Np/m
Q4.	What is the value of P3?
	P3=	W
Q5.	What is the value of P4?
	P4=	W
Q6.	If the meat is allowed to cook for 5 minutes, how much energy will have been absorbed by the steak?
	Wabs=	J
