Apparatuses for studying possible physical effects of dark matter may include an electronic oscillator. A power source may be in electrical communication with the electronic oscillator. An antenna may be in series electrical communication with the electronic oscillator. A first diode may be in series electrical communication with the electronic oscillator and the antenna. A second diode may be in series electrical communication with the electronic oscillator and the antenna. The first diode and the second diode may ensure and restrict flow of electrical current in one direction only in the antenna. Methods for studying possible physical effects of dark matter are also disclosed.
