Knowledge Base

The icon_import button includes options to import from a variety of formats:



This page provides an example to show how to import STL-formatted files into the layout editor.



This file format is commonly used to store 2-dimensional geometric data.



Tthis tool is useful for importing data from an atomic force microscope (AFM). In two dimensional simulations, the data must be defined as y = f(x). In three dimensional simulations, it must be defined as z = f(x,y). Both upper and lower surfaces can be imported.


icon_import_surf(n,k) material

The REFRACTIVE INDEX (N AND K) as a function of space, for example, to represent doped material where the doping concentrations and optical loss are calculated in another software package. In two dimensions, the data is defined as n(x,y), k(x,y) and in three dimensions as n(x,y,z), k(x,y,z). Please note that the value of k is translated into a conductive (or plasma) model and is only valid at a the center frequency of the simulation. It should therefore only be used with single frequency simulations.


icon_import_surfBinary import

This section describes the data format for importing binary data to define an object. In this binary import, the data should have values of 1 or 0, indicating that the object is or is not present. Binary import



Imports images either in JPG or PNG format . For example, this tool is useful for importing from a scanning electron microscope (SEM) image. In three dimensions, the imported data is extruded along the z axis.



Imports spatial liquid crystal (LC) orientation data from a CSV file. This file is typically created with TechWiz LCD from Sanayi System Co., Ltd. ( and makes it easy to import spatial information on LC orientation from TechWiz LCD simulations.


Obfuscating import data

In some cases it may be necessary for a party A to generate binary or n,k import data and send it to party B. Party A may not want party B to be able to see the actual structure that is being simulated. This section explains a capability that can solve this problem.
