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 ...

Comets continued to grab the limelight in the new year as well, with C/2025 R3 scheduled to fly by Earth in the coming months. It follows a string of other comets that made headlines in the past two ...

Abstract: This paper discusses the applicability conditions of the Physical Optics (PO) approximation and investigates its predictive power for far-field diffraction patterns of Reconfigurable ...

Abstract: In this communication, we present the modeling, design, and experiments of a wideband high-efficiency transmit-reflect-array (TRA) antenna with independent manipulations for transmitted and ...
