Bent Waveguide

Here, we demonstrate the propagation through bent waveguides with different bending radii. The thickness of all waveguides are same and let's denote as "d" here. Then we have 3 cases where the radius of bending is d, 2d or 3d. With the smaller radius, the leakage from the bending is stronger compared to the other ones.

Estimating Pi

Here, we look at the Archimedes' method to calculate/estimate the Pi number where simpler polygons are used to find the area of a unit circle. The video is inspired from a talk given by MIT Professor John Guttag within MITx - 6.00.2x.
