In Part 1, we introduced the phased array concept, beam steering and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of ...

Abstract: In this contribution, the Ewald method has efficiently been applied to accelerate the computation of the rectangular waveguide Green’s functions (GFs) derivatives. Based on previous works, ...

Vector graph or chart of exponential function with formula or equation f(x) = ax, or f(x) = exp x. The mathematical operation, basic function. Graph with grid and coordinates isolated on white.

If you’re taking an algebra, geometry or calculus class, your instructor will likely require a graphing calculator for your course. A graphing calculator is an essential tool for visually ...

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function \(y = ax^2 + bx + c \) has a minimum turning point when \(a \textgreater 0 \) ...

I was looking for a way to plot the tangent (small sectant) at a point and then move it along the graph. I could succeed with the first part but could not move it (and I tried to find it in the old ...

Graphs and data plots are wonderful tools for illustrating relationships, depicting data trends, and tracking goals in your Android applications. I saw this for myself several years ago, when a former ...

In the human brain, a default mode or task-negative network shows reduced activity during many cognitive tasks and is often associated with internally-directed processes, such as mind wandering and ...
