Spurious relationship — In statistics, a spurious relationship (or, sometimes, spurious correlation or spurious regression) is a mathematical relationship in which two events or variables have no direct causal connection, yet it may be wrongly inferred that they do, due … Wikipedia
Interference (wave propagation) — Two point interference in a ripple tank. In physics, interference is the phenomenon in which two waves superpose each other to form a resultant wave of greater or lower amplitude. Interference usually refers to the interaction of waves that are… … Wikipedia
Plane wave expansion method — (PWE) refers to a computational technique in Electromagnetics,solve the Maxwell s equations by formulating an Eigenvalue problem out of it. This method isa popular among Photonic Crystal community, as a method of solving for the band structure… … Wikipedia

Radio transmitter design — In plate modulation systems the voltage delivered to the stage is changed. As the power output available is a function of the supply voltage, the output power is modulated. This can be done using a transformer to alter the anode (plate) voltage.… … Wikipedia
