A Brief Review of High-Frequency Gravitational Waves

In this paper gravitational waves in high-frequency limits were briefly reviewed. A general formalism was derived for approximating gravitational wave solutions to the vacuum Einsteinequations of general relativity in situations where the gravitational fields are quite strong. To accomplish this by assuming that the wave has a high-frequency limit and expands the vacuum field equations in powers of the correspondingly small wavelength, getting an approximation scheme valid for all orders of ...
