Module 8.2: Medium-contrast Interface

Given: A 300-MHz plane EM wave in air (Medium 1) incident upon the planar boundary of a lossless dielectric medium with _r = 9 (Medium 2).

Q1.	What is the wavelength of the incident wave?
	1=	m
Q2.	What is the wavelength in Medium 2?
	2=	m
Q3.	What are the intrinsic impedances of Media 1 and 2?
	1=
	2=
Q4.	What is the reflection coefficient at the boundary?
	=
Q5.	What is the transmission coefficient into Medium 2?
	=
Q6.	If the amplitude of the incident electric field is 10 V/m, what would be the amplitudes of the total fields in Media 1 and 2?
	|E1|max=	V/m
	|E2|max=	V/m
Q7.	The combination of incident and reflected waves generates a standing wave pattern in Medium 1. How far from the interface in Medium 1 is the location of the first electric field maximum?
	lmax=	m
Q8.	What is the location of the first electric field minimum in Medum 1?
	lmin=	m
