Possibility to construct a gravitational wave detector by utilizing the electrogravitic property of dielectric materials

Takaaki Musha

Astronomers tried to detect gravitational waves, which are generated by the movement of massive astronomical bodies. However, it is very difficult to detect gravitational waves by using a massive transducer such as a Weber detector. According to the theory by Boyko Ivanov, the gravitational field can be induced by an external electric field. By studying IvanovÂ’s theory, the author has obtained the result that a gravitational wave detector consisting of a dielectric material, which has a higher sensitivity and a smaller size compared with the conventional gravitational detector, can be constructed. To verify the theoretical analysis, the author attempted to detect gravitational waves from the Crab Nebula by using a piezoelectric transducer and obtained a candidate detection.
