[理工] [電磁]多層膜
A 500MHz uniform plane wave is normally incident on a freshwater
(εr=88) lake covered with a layer os ice (εr=3.2) ,as shown
in Fig.P4.
(1)Find the minimum thickness of the ice such that the reflected wave
has a maximum strengh. Assume the lake water to be very deep.
(注意:他的要求是"最大"強度的反射係數哦 不是"零"反射係數)
(2) What is the ratio of the amplitude of the reflected and incident
electric fields ? (就是在問反射係數的絕對值 )
