In this work, a shared-aperture dual-band FZP metalens antenna is proposed by merging two single-band FZP metalens antennas, operating at distinct frequency bands, seamlessly into one. Instead of using conventional metallic conductors, double-screen meta-grids are devised in this work to form the concentric rings.

Moore’s law is coming to an end according to many science and technology commentators. Among them is the celebrity theoretical physicist Michio Kaku who predicted in 2012: “In about ten years or so, we will see the collapse of Moore’s law.”

If you’re a designer of extremely high-speed PCBs or high-frequency RF devices, then you’ll be taking advantage of impedance controlled routing features in your PCB design software. These tools are designed to ensure the impedance of a transmission line is consistent along its length, thereby allowing termination at each end to prevent reflections. Consistent impedance...

Learn how integrating piezoelectric thin film with multi-material metal-and-dielectric 3D printing, can produce flexible sensors that are suitable for testing opto-electro-mechanical performance and biochemical sensing.

When only a small number of designs ran at extremely high speeds (<1 ns rise times), most designers did not worry so much about the fiber weave effect in PCB design and manufacturing. With low bandwidth digital signals and at low GHz frequencies, the effects of a loose fiber weave were generally too small to...

Whether you work on high-speed digital or high-frequency analog devices, losses and signal distortion are important performance metrics in these systems. In planar PCBs on rigid substrates, the industry is moving away from FR4 PCBs, and a variety of high-speed laminate materials are available with low losses and nearly flat dispersion. Despite the availability of...

Mass manufacturing has made modern life possible for people around the globe. The need to quickly manufacture products in high volumes is not going to change any time soon, but the traditional production environment is not suitable for high-mix, low-volume manufacturing of complex products. This is especially true for a number of plastic and mechanical...
