Abstract: The substrate integrated waveguide (SIW) comprising rectangular via-holes is herein treated by a rigorous full-wave modal analysis using the moment method entailing Green's functions for ...

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 ...

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.

A mathematical function is a formula that takes an input, x, applies a set of calculations to it, and produces an output called y. By calculating a function at a large number of set intervals, it is ...

Anyone who’s taken classes in geometry, algebra, trigonometry or other advanced math forms has certainly encountered the graphing calculator before. These multi-function devices make incredibly ...

A comical illustration of quantum tunneling. Suppose you are running towards a wall, presuming you’re not a very bulky person but just an average human supposedly you’ll hit your head, and the rest is ...

Let's imagine that you are in a car with no windows. I know that's crazy, but just hold on. Although there are no windows, you can see the speedometer. So here is the question. Is it possible to ...

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 \(a \textgreater 0 \) ...
