一个监视器的transmission转换为dB：

monitor0="drop";

T_temp =getresult(monitor0,"T");

x=T_temp.lambda;

x=1000000000*x;

y=10*log10(T_temp.T);

plot(x,y,"Wavelength(nm)", "Transmission(dB)","Simulated response","linewidth =5" );

两个监视器的transmission转换为dB后比较：

monitor0 = "out";

monitor1 = "in";

T_out=getresult(monitor0,"T");

T_in =getresult(monitor1,"T");

x=T_out.lambda;

x=1000000000*x;

y1=10*log10(T_out.T);

y2=10*log10(T_in.T);
