Title: Innovations of Rana Biswas
Introduction
Rana Biswas is an accomplished inventor based in Ames, IA (US). He has made significant contributions to the field of photonic crystals, holding a total of 4 patents. His work focuses on advanced manufacturing methods and antenna technologies that leverage the unique properties of photonic bandgap materials.
Latest Patents
One of his latest patents is a manufacturing method of photonic crystals. This method involves the conformal deposition of a high-refractive-index material on a periodic template made of a low-refractive-index material through an atomic layer deposition process. This technique enhances the difference in refractive indices or dielectric constants, enabling the formation of a three-dimensional photonic crystal with a superior photonic bandgap. The three-dimensional structure can be prepared using a layer-by-layer method.
Another notable patent is for highly directional receiver and source antennas utilizing photonic bandgap crystals. This invention features a directional antenna constructed with two photonic bandgap structures oriented back to back, separated by a distance that creates a resonant cavity. An antenna element is positioned within this cavity, and the resonant frequency can be adjusted by varying the distance between the photonic bandgap structures, allowing for both asymmetrical and symmetrical configurations.
