Abstract We experimentally demonstrate a Purcell effect-based design technique for improved impedance matching. and thus enhanced the reflection coefficient from a small microwave emitter. Using an iterative process centred on comparing the phase of the radiated field of the emitter in air with that of the emitter in a dielectric environment. we optimise the structure of a dielectric ... https://www.roneverhart.com/Krave-Glass-Beaker-Orb-FREE-GRINDER/
