The gravitational field of the sun acts as a spherical lens to magnify the intensity of radiation from a distant source along a semi-infinite focal line. A spacecraft anywhere on that line in principle could observe, eavesdrop, and communicate over interstellar distances, using equipment comparable in size and power with what is now used for interplanetary distances. If one neglects coronal effects, the maximum magnification factor for coherent radiation is inversely proportional to the… 
Interstellar radio links enhanced by exploiting the Sun as a Gravitational Lens
Abstract The gravitational lens of the Sun is an astrophysical phenomenon predicted by Einstein’s general theory of relativity. It implies that if we can send a probe along any radial direction away
Mission to the Gravitational Focus of the Sun: A Critical Analysis
The gravitational field of the sun will focus light from a distant source to a focal point at a minimal distance of 550 Astronomical Units from the sun. A proposed mission to this gravitational focus
Diffraction Pattern of Solar Gravitational Lens
We consider scattering of electromagnetic waves from a distant source by the gravitational field of the sun, taking the sun oblateness into account. It turns out that the sun oblateness is of a great
A new belt beyond Kuiper's: A belt of focal spheres between 550 and 17,000 AU for SETI and science
Abstract Gravitational lensing is one of the most amazing discoveries produced by Einstein's general theory of relativity. To date, hundreds of gravitational lenses have been observed by astronomers
The gravitational lens as an intergalactic communication tool
Abstract The gravitational lens, a consequence of general relativistic light bending with perfect or near-perfect observer-bender-object alignment, is now a well-studied natural phenomenon. Primarily

Several recent works have proposed a “stellar relay” transmission system in which a spacecraft at the focus of a star’s gravitational lens achieves dramatic boosts in the gain of an outgoing or
Tethered system to get magnified radio pictures of the galactic center from a distance of 550 AU
Abstract The mass of the Sun is by far the largest mass in the solar system. The light-bending effect predicted by general relativity is thus by far larger around the Sun than around any other body
Interstellar communication. II. Application to the solar gravitational lens
Abstract We have shown in paper I of this series [1] that interstellar communication to nearby (pc) stars is possible at data rates of bits per second per Watt between a 1 m sized probe and a large
Laser Communication with Proxima and Alpha Centauri using the Solar Gravitational Lens
A search was conducted for laser signals, both sub-second pulses and continuous emission, from the regions of the sky opposite Proxima and Alpha Centauri. These regions are located at the foci of the
The 550‐au Mission: a critical discussion
We have studied the science rationale, goals and requirements for a mission aimed at using the gravitational lensing from the Sun as a way of achieving high angular resolution and high signal

Deep radio occultations and ``evolute flashes'' their characteristics and utility for planetary studies
Abstract Radio occultation studies of the structure of planetary atmospheres have generally involved relatively shallow penetration of the spacecraft behind the limb of the planet in the plane of the
Extraterrestrial Intelligence: An Observational Approach
TLDR
The microwave region of the electromagnetic spectrum, a plausible regime for signals from extraterrestrial intelligences, is largely unexplored, and an all-sky, broad-band survey lasting perhaps 5 years can be structured so that even negative results would establish significant boundaries on the regime in which such signals may be found.
Eavesdropping: the radio signature of the Earth.
TLDR
The case of planet earth is considered to understand better the information which might be derivable from radio leakage, and a model including over 2000 television transmitters is used to demonstrate the wealth of astronomical and cultural information available from a distant observer's careful monitoring of frequency and intensity variations in individual video carriers.
