Rigorous Coupled-Wave Analysis (RCWA)

This RCWA MATLAB code was initially developed in Professor Zhuomin Zhang’s group at Georgia Tech in 2007. It has been improved and tested since then and used in a large number of publications from Prof. Zhang’s group. A tutorial providing some basic examples on how to use the code, and some of the material property data files from literature are included in the package. Approved by Zhuomin Zhang, October 1, 2014, for free release and distribution.

Rad-Pro Software

 

Consider the following case. The silicon wafer is coated with a 300-nm silicon dioxide layer on both sides. The thickness of silicon wafer is 700 mm, and silicon is doped with phosphorus (n-type) at 1016 cm-3. To consider the doping effects, the Drude model is used. The temperature of silicon wafer with thin-film coatings is 500 °C, and the electromagnetic waves are incident at q = 0°. The considered wavelength range is from 0.5 mm to 10 mm in every 0.01 mm, and the incoherent formulation is used for calculation.

 

Input Parameters

• Considered wavelength region:

0.5 - 20 mm

• Room temperature

• Normal incidence

• Incoherent formulation

  

Calculation Results

 

 

The Rad-Pro software (Excel file and calculation module) is attached as a ZIP format, and the Rad-Pro manual is in PDF format. Copy module.dll into your main (C:) directory. To download, click the following links.

  • Users are welcome to provide feedback for further improvement and upgrade.
  • Version note: There was a problem in the calculation of the hemispherical emissivity in the previous version (version 1.1), but it has been resolved in the current version. 
  • Version note: Version 1.2 is corrected to account for recent Microsoft Office releases (Excel 2010 and 2007). Some minor capabilities programmed in the VBA source code may not work.
