Abstract: In this paper a simple and efficient ray-tracing model is presented to evaluate two-dimensional (2D) multilayer dielectric lenses combined with arrays. The proposed algorithm is capable of ...

Abstract: Compared to conventional 3D radar systems, 4D radar systems require higher angular resolution in both azimuth and elevation. Besides, sparse arrays offer several advantages, including ...

iOS 26 introduces Spatial Scenes, which use AI to turn flat photos into depth-rich, interactive images. The effect works even on older iPhones (iPhone 12 and newer) without the need for Apple ...
