Measuring the scattering parameters of a microwave transistor to develop an appropriate small-signal device model, the question may come up about the minimum frequency range needed to extract reliable model parameter values. This issue has been studied intensively for microwave devices based on GaN technology and discussed in detail in my book Parameter Extraction and …
Blockchain applications and limitations in Cyber-Physical Systems – CPS Cyber-Physical Systems (CPS) integrate sensing, networking, and computation capabilities where millions of networkable devices sense the environment to capture information. Using network infrastructure, mainly the Internet, the information is transferred to cloud servers where it is processed to offer personalized services to the users. The data …
Artech author Kenneth Hintz gave us insight into theories of sensor management: There is no single theory of sensor management due to the heterogeneity of sensors (physical, social, cyber, database), applicable mathematics (game theory, estimation, information, statistics, probability), and users with different needs (strategic, tactical) and values (local, national, political, ethical). What started out as …
Artech author Ken Hintz gave us insight into today’s sensing environment: Today’s sensing environment not only contains the conventional military physical sensors such as RADAR, FLIR, LIDAR, ESM, etc., but also includes widely distributed physical environmental sensors in the internet of things (IoT). The number of civilian networked devices comprising the IoT was an estimated …
How Lithium Ion batteries are made Readers get a hands-on understanding of Li-ion technology, how Lithium Ion batteries are made, Lithium Ion battery chemistry, they are guided through the design and assembly of a battery, through deployment, configuration and testing, Lithium Ion battery advantages as well as Lithium Ion battery safety and avoiding accidents. Lithium-Ion …
When Artech House authors write their books, we ask them what they want their readers to get out of the project. In this series, we show you what our authors, in their own words, wish to impart upon readers. Warren Stutzman, author of Polarization in Electromagnetic Systems, Second Edition, describes what his book is about: …
My published book titled Parameter Extraction and Complex Nonlinear Transistor Models concerns with the following three key topics: Small-signal model parameter extraction Large-signal device modeling Large-signal measurement techniques In my first post, dated December 17, 2019, I explained the limitation of using the standard 15-element FET model for modern high power multifinger GaN devices. Similar …
Artech House supports its authors long after their books publish, and our authors continue to make huge strides in their fields. Today, we highlight author Tom Otoshi, whose book, Noise, Temperature Theory and Applications for Deep Space Communications Antenna Systems, continues to be relevant today: In 1961, Mr. Otoshi joined the Jet Propulsion Laboratory (JPL) at …
Cameron Coursey, who just released his second book with Artech House, The Practitioners Guide to Cellular IoT, describes what compelled him to write his book, and gives us a look at how he got into his field of IoT. What prompted me to write my book: There is a scene in the movie Apollo 13 …
