Optical polarimetric measurement of surface acoustic waves
Kotaro Taga, Ryusuke Hisatomi, Yuichi Ohnuma +4
Surface acoustic wave (SAW) is utilized in diverse fields ranging from physics, engineering, to biology, for transducing, sensing and processing various signals. Optical measuremen…
Gravitational lens without asymptotic flatness: Its application to the Weyl gravity
Keita Takizawa, Toshiaki Ono, Hideki Asada
We discuss, without assuming asymptotic flatness, a gravitational lens for an observer and source that are within a finite distance from a lens object. The proposed lens equation i…
Gravitational deflection angle of light: Definition by an observer and its application to an asymptotically nonflat spacetime
Keita Takizawa, Toshiaki Ono, Hideki Asada
The gravitational deflection angle of light for an observer and source at finite distance from a lens object has been studied by Ishihara et al. [Phys. Rev. D, 94, 084015 (2016)],…
The effects of finite distance on the gravitational deflection angle of light
Toshiaki Ono, Hideki Asada
In order to clarify effects of the finite distance from a lens object to a light source and a receiver, the gravitational deflection of light has been recently reexamined by using…
Deflection angle of light for an observer and source at finite distance from a rotating global monopole
Toshiaki Ono, Asahi Ishihara, Hideki Asada
By using a method improved with a generalized optical metric, the deflection of light for an observer and source at finite distance from a lens object in a stationary, axisymmetric…
