You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise) in-place. You have to rotate the image in-place, which means you have to modify the input 2D matrix ...

Abstract: This paper proposes a large-spacing scanning phased array based on U-slot patch antennas. A genetic algorithm is used to optimize the beamforming for a $1 \times 5$ subarray. And taking into ...

Abstract: This letter presents a conformal microstrip array antenna and an associated imaging algorithm for microwave brain hemorrhage diagnostic systems. Each antenna element utilizes a ...
