The camera system has two cameras and the center of the two cameras is the position of the camera system. The point of my interest is P, which is translated from the position of the camera system by ...

Abstract: A novel application of 4 × 4 Butler matrices in a multiport measurement technique has been investigated. The proposed measuring system consists of two standard Butler matrices. By ...

Abstract: The paper presents the design of ultra wideband (UWB) 4times4 and 8times8 Butler matrices in multi-layer microstrip-slot technology that are aimed for inclusion in UWB switched-beam smart ...

The following example demonstrates a problem with the implementation of Canvas where it accepts 4x4 matrices in its transform() method, but it does not compose the matrix appropriately if there are ...

Ultra-broadband microwave component and test equipment developer KRYTAR Inc. has launched three new 4×4 ButlerMatrices with ultra-broadband frequency coverage from 1.0 GHz to 40.0 GHz. A Butler matrix ...

To describe 1) how to determine toric (posterior chamber) intraocular lenses (IOLs) with standard formulas, 2) a matrix-based calculation scheme for determining toric IOLs using 4x4 matrices, 3) a ...
