Engineering Crossword Puzzle w/Weekly Headlines, July 22

RF Cafe Engineering Crossword Puzzle w/Weekly Headlines July 22, 2018At least 10 clues with an asterisk (*) in this technology-themed crossword puzzle are pulled from this past week's (7/16 - 7/20) "Tech Industry Headlines" column on the RF Cafe homepage. For the sake of all the avid cruciverbalists amongst us, each week I create a new technology-themed crossword puzzle using only words from my custom-created list related to engineering, science, mathematics, chemistry, physics, astronomy, etc. You will never find among the words names of politicians, mountain ranges, exotic foods or plants, movie stars, or anything of the sort. You might, however, see someone or something in the exclusion list who or that is directly related to this puzzle's theme, such as Hedy Lamar or the Bikini Atoll ...

 

 

 

 

 

 

 

 

 

 

25 Charts on Spectrum Ownership in the United States

25 Charts on Spectrum Ownership in the United States - RF Cafe"Licensed spectrum remains the lifeblood of the cellular industry. But which companies actually own all those spectrum licenses? More importantly, which spectrum licenses do they own, how much did they pay for them, and where is the market heading? This report aims to answer these questions. We've collected the below charts from a variety of sources including spectrum management companies, Wall Street analyst firms and boutique analysis companies such as Allnet Insights & Analytics. Our goal is to provide an overview of licensed spectrum ownership in the United States ranging from low-band licenses like 600 MHz to high-band holdings up to 40 GHz ..."

Electronic Stickers to Streamline Large-Scale IoT

Electronic Stickers to Streamline Large-Scale IoT - RF Cafe"Researchers have developed a new fabrication method that makes tiny, thin-film electronic circuits peelable from a surface. The technique not only eliminates several manufacturing steps and the associated costs, but also allows any object to sense its environment or be controlled through the application of a high-tech sticker. Billions of objects ranging from smartphones and watches to buildings, machine parts and medical devices have become wireless sensors of their environments, expanding a network called the 'internet of things.' As society moves toward connecting all objects to the internet - even furniture and office supplies ..."

China Plans 2 New Gravitational-Wave Missions

China Plans 2 New Gravitational-Wave Missions - RF CafeThis is worth looking at just for the cool image. "China has revealed plans for two space-based missions to study gravitational waves. The National Space Science Center, Chinese Academy of Sciences (CAS), announced on 4 July that the country will launch a mission in 2020 to monitor gamma-ray bursts associated with gravitational-wave events. The CAS also gave the go-ahead for a fully-fledged gravitational-wave detector to be sent into space in 2033. Gravitational waves are distortions of space-time that occur when massive bodies, such as black holes, are accelerated. Since their first direct detection in 2015 by the Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors ..."

Experts and Engineers Explain 10 Steps of Design Process

Experts and Engineers Explain the 10 Steps of the Engineering Design Process - RF Cafe"The 10 steps of the engineering design process are fundamental knowledge for all budding engineers. If you're hoping to become an engineer, one of the most crucial things you need to learn are the 10 steps of the engineering design process. This process lays out the correct protocol for any project, allowing everything to go seamlessly. No matter which area of engineering you intend to work in, the 10 steps will always be important. They're a fundamental part of engineering, and can always provide a solid foundation for your work. Let's take a look at each step, and hear what the experts have to say about the importance of the process ..."

Nanoparticles Enable Molecular Electronic Devices

Nanoparticles Enable Molecular Electronic Devices - RF Cafe"Last week, researchers at IBM Research-Zurich in Switzerland, and the Universities of Basel and Z├╝rich announced in a Letter published in Nature a new method for creating electrical contacts to individual molecules on a silicon chip. The advance could open up a promising new way to develop sensors and possibly other electronic or photonic applications of manipulating single molecules. When, in the mid-1970s, researchers discovered single molecules with interesting electronic properties such as that of a diode, hopes were high that this would spur the development of a new semiconductor technology that might compete with silicon-based electronics ..."

A Photonic Circuit for Quantum Computers

A Photonic Circuit for Quantum Computers - RF Cafe"Getting photons to interact is a key step toward using them as qubits. The foundational element of quantum computers is the qubit. Qubits can be any kind of particle that has quantum properties, such as an electron or a photon. For these qubits to accomplish their job in a quantum computer, they need to interact with each other in a quantum process known as entanglement. While photons would make for great qubits because of their speed, they don't like to interact with each other, or anything else for that matter, making it difficult to achieve quantum entanglement. Now researchers at the University of Maryland and the Joint Quantum Institute have managed ..."

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
