Google's Food Detection Algorithm is Not Bad

I was scrolling through Google photos when I noticed they had auto-categorized some of my pictures. Overall I have to say their algorithm was not too bad. It was able to recognize (from left to right) a watermelon, a microscope picture of a strawberry and a microscope picture of homemade bread. Taken with my smartphone microscope of course.

It trips up a bit when it gets to what the majority of my photos contain ... bike horns. These particular images show me digitally marking up an early 3D printed horn prototype to communicate design changes to Chris, the industrial designer for Loud Bicycle.

While we are on the topic, please check out the Kickstarter for the new bike horn that will be even better than the last horn. As of this posting we have not yet reached the goal, so please support it!

And for that I present what I think is the very first animated GIF in LanseyBrothers Blog history.

Seriously though, have we ever had an animate gif before?

National Grid has absolutely no idea who we are, so they addressed the envelope to "Or Current Resident"

A new paper

I just had a paper, "Measurement of Photon Sorting at Microwave Frequencies in a Cavity Array Metasurface" (based on some of my dissertation work, believe it or not) published in IEEE Transactions on Antennas and Propagation. It was a ridiculous review process and I owe many thanks to Isroel Mandel for his efforts getting this darn thing published. This is not an open-access paper, so let me know if you want a copy.

The basic idea in this paper is an experimental extension of previous results. In the previous paper, we demonstrated in simulation how electromagnetic fields are spectrally and spatially split into different regions of a metamaterial structure. In this paper we report how we measured this field splitting:
We also demonstrated how this method might be expanded to include three different, distinct absorption frequencies.

For the rest of the info, read the paper!
