that before researchers can sprint off to the races using poly- meric inks, they must first learn to walk. The first step is digging into the intersection of the macro scale and the nano scale.

more necessary for implement- ing 5G technology in the mil- limeter-wave range as these waves are much more prone to interference. This has led re- searchers to investigate BFNs and improve them to provide low cost-solutions for single-layer PCB implementation. In other words, the goal is to produce a configuration with the maxi- mum number of beams and the lowest number of layers. Scientists from Tokyo Tech,
Japan, and the European Space Agency, The Netherlands, have introduced a novel one-dimen- sional switching matrix that achieves a reduction in the num- ber of layers when compared to conventional matrices. The novel matrix topology

overcomes the limitations of con- ventional beamforming matri- ces. While Butler matrices are limited in the number of beams they can generate to integer powers of two, the proposed solu- tion can generate an arbitrary number of beams. Unlike Nolen matrices, an even distribution of the signals between the phase shifters and directional couplers is possible, resulting in more uniform output signals. Compared to the conven-

promise because of their many functionalities. One advantage of 3D printing is near-complete con- trol over the final product’s shape. The conductivity of Abadi
and Kasraie’s nanomaterial ink is an exceptionally handy trait that gives the printed epoxy the potential to double as electrical wiring — whether in a circuit board, an airplane’s wing or in 3D-printed actuators for guiding catheters in blood vessels. Anoth- er useful trait of the nanocompos- ite polymer ink is its strength. Property-to-weight ratio, electri- cal conductivity,

strength and ease of application are just a few of the many prom- ising reasons why polymer nanocomposite inks will likely re- place traditional epoxies. Web:
