問題詳情

4.For a coaxial transmission line shown in Fig. 2, the capacitance per unit length is

and the inductance per unit length is

. At high frequencies, the intemalinductance drops off (that is, approaching 0, and you should know which term is the internalinductance).

【題組】(4%)(a) Eind the characteristc impedance ofthe coasial line

at high frquencies請務必將 internal inductance拿掉,並寫Zc之單位(即簡化

)。
