WebMar 17, 2024 · RF reflection results in attenuation and interference Signals can be reflected whenever there is a mismatch in characteristic impedance. However, it rarely causes any problem at low speeds. RF reflection becomes a concern when the trace or conductor’s length is equal to or larger than 1/4 of the signal’s wavelength. WebJul 22, 2024 · You need a retroreflector, which is a special type of reflector that sends light back towards its source (unlike a simple mirror). This is what you'd put on the rear of your bicycle to reflect the headlights of incoming drivers back at them so they see you at night. You can get them for cheap in any bicycle store or supermarket.
