Toshiro Kodera: Electromagnetic Gyrotropes

We’ve learned a lot by watching the talks from the Hackaday Superconferences. Still, it’s a rare occurrence to learn something totally new. Microwave engineer, professor, and mad hacker [Toshiro Kodera] gave a talk on some current research that he’s doing: replacing natural magnetic gyrotropic material with engineered metamaterials in order to make two-way beam steering antennas and more.

If you already fully understood that last sentence, you may not learn as much from [Toshiro]’s talk as we did. If you’re at all interested in strange radio-frequency phenomena, neat material properties, or are just curious, don your physics wizard’s hat and …read more

Physics or Phiction?

Do you remember Gilligan’s Island? For many people of a certain age, “The Professor” was our first impression of what a scientist was like. Even in those simpler times, though, you probably couldn’t find anyone like the professor; a jack of all trades, he sort of knew everything about everything (except, apparently, how to make a boat).

Real scientists tend to hyper-specialize. Getting grant money, publication pages, and just advancing the state of the art means that you get more and more focused on more obscure things. It is getting to the point that two scientists in the same field …read more
