Nanoantenna Phasor Lab: Interference of Coupled Dipoles

The 3D version of this simulator renders a Yagi-Uda nanoantenna as rods in space with a lobe curve floating in front of them. This 2D companion solves the identical coupled-dipole linear system — the same Green's function coupling, the same driven feed plus passive reflector and directors — but puts the raw complex numbers on screen instead: a bank of rotating phasors for each rod's dipole moment, a 2D polar radiation plot you steer with a draggable observation angle, and a scope trace where each rod's individual sinusoid is drawn faintly so you can watch them physically add up into the forward lobe or cancel into the null behind the reflector.
