Hello<br />
Do you find that if you use the same incident field for example E0*exp(-j*(emw.k0*x*sin(phi)+emw.k0*z*cos(phi)), but select the different boundary as the input, the wave direction is different, do you know why?<br />

I think you can type E0*exp(-j*(emw.k0*x*sin(phi)+emw.k0*z*cos(phi)) in the "incident field", or you can just set kx=k0*sin(phi), ky=k0*cos(phi) in the "wave direction"<br />

Hello,<br />
<br />
I am not sure about second way. I used first way: E0*exp(-j*(emw.k0*x*sin(phi)+emw.k0*z*cos(phi)). I always use incidetn field, not wave direction. <br />
<br />

I want to know that you use the scattering boundary condition or the Port to input the light, and how do you set the wave direction or the propagation constant<br />

<br />
I used scattering boundary condition, but I am nor sure that I understoood second question about equation. <br />

Dear All,<br />
<br />
I have issue. I have one metal block on substrate, and I want to illuminate it but at some angle (picture). <br />
<br />
One half sphere is substrate, one half air. <br />
<br />
Now I want to apply x polarization, scattered field.<br />
<br />
<br />
I have two cases, first when substrate is also air, and second when substrate is glass (with index refraction ns). <br />
<br />
In the case when substrate is air I applied equation: E0*exp(-j*(emw.k0*x*sin(phi)+emw.k0*z*cos(phi)).<br />
<br />
In the case when substrate is glass I applied equation: E0*exp(-j*(emw.k*x*sin(phi)+emw.k*z*cos(phi)).<br />
<br />
<br />
Or maybe in second case I have to write: <br />
<br />
(1-sign(z))*E0*(-j*2*pi*x*sin(phi)/Lambda-j*2*pi*z*cos(phi)/Lambda)/2 +<br />
<br />
+ (1+sign(z))*E0*(-j*2*pi*x*sin(phi)*ns/Lambda-j*2*pi*z*cos(phi)*ns/Lambda)/2 <br />
<br />
<br />
Tell me please for any of these equations are they correct.<br />
<br />
<br />
Thank very much in advanced.Sat, 03 Nov 2012 15:31:54 +000032722.1351956714.89562
