## Reflectance / Transmittance calculation using PORT

Posted 09/01/2013, 01:53 GMT-05:00 RF & Microwave Engineering Version 4.3a 5 Replies

Hello all

I want to calculate effect of nanostructure on reflectance and transmittance.

As a starting point, I have refered "Fresnel equation" library.

Without any nanostructure, the calculated reflectance is well matched with theorectical value!

So.. one thing I want to know is that the same port boundary condition can be applied to a model system with 3D nano structure? (Simply, air/Nanostructures on substrate/substrate)

Also, I want to calculate the reflectance using input and output power.

Output power can be calculated using integration of time-averaged power outflow (nPoav).

However, I don't know how to know incident power when I use scattering boundary condition, or electric field condition.

Would you comment on this?

<Summary>

1. Using same model of "Fresnel equation" library, can reflectance of a system with 3D nano structure be calculate?

2. How can I calculate incident power of light, when I use electric field boudnary condition?

Thanks!
