Microwave Magazine January 2023

The January 2023 issue of the IEEE Microwave Magazine is now out. We have a wide variety of features in this issue. We have fabrication features regarding additive manufacturing and gap waveguide technology as well as an energy harvesting feature reviewing rectifier circuits. And who doesn’t love 3D printing? We have an article covering everything from the history of 3D printing to printing conductors in substrates. Recently researchers have taken the old idea that if making a hard metal connection is difficult at short wavelengths – then use a gap. And our circuit design feature is everything you always wanted to know about rectifiers. We also have 15 columns so this issue is a real treat for everyone.
