Abstract: The paper presents a linear phased array antenna comprising finite number of coupled multimode waveguides of square cross section. The waveguide design that allows increasing effective area ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value. If target is not found in the array, return [-1, -1]. You must write an ...

Abstract: The use of Focal Plane Arrays (FPA) as feeds for reflector antennas constitutes a new-generation solution for future radio telescope systems. In this paper, we investigate one of two main ...

In Java, arrays are useful data structures that store elements of the same data type sequentially in memory. Frequently, developers need to determine the size of an array for various reasons like ...

Now, let’s see these in detail. TypoExample.java:5: error: cannot find symbol System.out.println("The value is: " + numer); // Typo 1 ^ symbol: variable numer ...

ABSTRACT: In high frequency surface wave radar (HFSWR) applications, range and azimuth resolutions are usually lim-ited by the bandwidth of waveforms and the physical dimension of the radar aperture, ...
