光電導(dǎo)天線仿真
在CST里仿真用于接收側(cè)的光電導(dǎo)天線,除了默認(rèn)的激勵(lì)信號(hào)之外,是否還要加發(fā)射側(cè)產(chǎn)生的光電流信號(hào)呢?有沒(méi)有做過(guò)光電導(dǎo)天線的仿真,來(lái)交流一下,謝謝!
在一篇論文里看到了這段話:The default signal i1(t), which is a Gaussian-shaped excitation function in the desired frequency range, is used to drive the signal in the gap of the antenna with a discrete port. This selection guarantees that the stability in the simulationis achieved regardless of the photocurrent signal duration.(默認(rèn)信號(hào)i1(t)是期望頻率范圍內(nèi)的高斯型激勵(lì)函數(shù),用于驅(qū)動(dòng)天線間隙中的信號(hào),該信號(hào)具有離散端口。這種選擇保證了無(wú)論光電流信號(hào)持續(xù)時(shí)間如何,模擬的穩(wěn)定性都能實(shí)現(xiàn)。),所以在想光電流信號(hào)是否要加,如果要加,是通過(guò)波導(dǎo)端口還是離散端口還是其他方式加上,再進(jìn)行接收側(cè)天線的仿真?
