求助:计算绘图
 

源程序在附件中,做一个积分运算,并作图,但显示无法计算,请各位帮忙!!

f = 130;
\[CapitalOmega] = ArcTan[(0.5*l)/f];
Subscript[\[Phi], 2] =
ArcSin[Subscript[n, 1]/Subscript[n, 2]*Sin[Subscript[\[Phi], 1]]];
Subscript[\[Tau], s] =
1 + (Subscript[n, 1]*Cos[Subscript[\[Phi], 1]] -
Subscript[n, 2]*Cos[Subscript[\[Phi], 2]])/(

Subscript[n, 2]*Cos[Subscript[\[Phi], 2]]);
Subscript[\[Tau], p] =
1 - (Subscript[n, 2]*Cos[Subscript[\[Phi], 1]] -
Subscript[n, 1]*Cos[Subscript[\[Phi], 2]])/(

\[CapitalPhi] = -k*

I[y_, z_] = \!\(

ContourPlot[I[y, z], {y, -10, 10}, {z, -20, 20}];

运行显示无法计算,还请各位帮忙,谢谢!
