Archimedes' Spiral Archimedes mathematically described the constant windings in a simple spiral. This shape can be found on the bottom of a pinecone. Sphere Archimedes studied spheres.

Similarly, place points (2,2), (3,3), and (4,4). If you continue to add dots in this way, the shape will gradually expand into a spiral and form a figure called the 'Archimedes spiral.' ...

While Archimedean spiral antennas were invented a half-century ago, only self-complementary impedance can be evaluated directly from the Babinet’s principle. This paper examines the effects of ...

A parametric analysis is performed for a wideband Archimedean spiral antenna in recognition of an emerging concept to integrate RFID along with several applications by using a single antenna. The ...

We recently reported a study on the generation and resonance of sound in a shell assuming the straightened conch-cavity as a truncated horn. However, the tomographic picture reveals that the cavity ...
