Abstract: A novel and accuracy phased array calibration method is presented in this paper. The method improves the rotating-element electric-field vector (REV) method, where the phase of each element ...

Explanation: Total number of unique elements are 3, i.e[1,2,3] and Therefore return 3 after assigning [1,2,3] in the beginning of the array. Explanation: Total number of unique elements are 4, i.e[1,2 ...

Per- and polyfluoroalkyl substances (PFAS) have been mass produced for decades in consumer products like frying pans, water-resistant clothing, food packaging and cosmetics. They have also been used ...

Abstract: The embedded element efficiency (EEE), which quantifies mutual coupling in antenna arrays, critically limits the signal-to-noise ratio in large-scale array communications. However, ...

Method references are a shorthand way to write lambda expressions that call a single method. Rather than implementing a method in a functional interface, a method reference simply points to an ...

As a practical approach to reflecting the properties of the formation, the slowness of near-wellbore formation is of great significance to geophysical exploration, which can be used to evaluate rock ...
