Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly reflecting shapes to tile a surface, researchers uncovered a method that links ...

Discover the science behind seeing your reflection in water. Light travels in straight lines and bounces off smooth surfaces, ...

Abstract: Positioning in indoor environments, where it is difficult to achieve an accurate performance using GPS or satellites, has been studied in various ways using several wireless communication ...

Abstract: This paper presents and experimentally validates various topologies of one-port reflective-mode phase-variation permittivity sensors based on weakly coupled step impedance resonators (SIRs), ...
