CST中監(jiān)視器應(yīng)設(shè)置錯(cuò)誤不會(huì)調(diào)整

小弟初學(xué)CST，想計(jì)算power loss dens，但是設(shè)置了power loss dens監(jiān)視器以后，計(jì)算時(shí)顯示無(wú)法計(jì)算，具體內(nèi)容為，the monitor loss is only available for dielectric or magnetic losses and will be ignored。請(qǐng)問(wèn)各位大俠我是有參數(shù)沒(méi)設(shè)置還是模塊選擇不對(duì)，我用的模塊是coupler(waveguide)!

這跟監(jiān)視器沒(méi)關(guān)系，而跟你的材料屬性中是否有損耗有關(guān)系，沒(méi)有損耗的介質(zhì)材料，何來(lái)Power Loss呢？
