Fully Metallic Reflectarray for the Ku-band Based on a 3D Architecture

Abstract

This document presents the design and manufacture of a reflectarray (RA) antenna for the Ku-band, based on a fully-metallic 3D architecture. The reflectarray unit cell is formed by a square-shaped waveguide section ended in a short circuit, that is the reflectarray back ground plane. Each cell has the ability of configuring the phase of its own reflected field by means of resonators perforated on the walls of the cell waveguide section. The resonator-based waveguide cell introduces the 3D character to the design. The geometry of the resonators and its size variation introduces the phase behaviour of each cell, conforming the radiation pattern of the reflectarray. This design explores the potential of phase value truncation (6 states and 2 states), and demonstrates that proper pattern results can be obtained with this phase truncation.

Research on Multi-sensory Experience Design of Zen Tea Culture--The Case of Innovative Design of Chinese Characters

“…Multi-sensory experience theory emphasizes the role of "perception" in emotional experience, which requires designers to use multiple senses as much as possible in the design process, so as to improve the added value of products or services. In the study of Zen tea culture, the multi-sensory experience theory mainly emphasizes the experience of people in multiple senses, including vision, hearing, smell, taste, etc., and through the comprehensive use of these senses, it can bring better experience to consumers [2].…”
