To ensure reliable fabrication of a device, it is crucial to avoid using feature sizes below a certain feature size when performing inverse design. To achieve this in level set optimization, you can use penalty functions to apply a substantial penalty to the objective function if the curvature and gap size values fall below a minimum feature size. This example shows how to calculate the minimum radius of curvature and the minimum gap size penalty functions using the level set surface as input.
