... You can see in the graph of f(x) = x2 + 1 below that f has no real zeros. If you solve the corresponding equation 0 = x2 + 1, you find that x = ,which has no real solutions. However, you can find solutions if you define the square root of negative numbers, which is why imaginary numbers were invente ...

... The empty sum is such a borderline case of sum where the number of the addends is zero, i.e. the set of the addends is an empty set. • One may think that the zeroth multiple 0a of a ring element a is the empty sum; it can spring up by adding in the ring two multiples whose integer coefficients are o ...

Why not use near field probes
... This makes it obvious that it is the aerial which radiates emissions, not the source. Near field probes are great for detecting the location and frequency of sources, but they give little information about the efficiency of the radiating mechanism, the aerial. So we can have a situation (and very fr ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
