Antenna design has evolved from bulkier to small portable designs but there is a need for smarter antenna design using machine learning algorithms that can meet today’s high growing demand for smart and fast devices. Here in this research, main focus is
In this work, we present a type of flexible and broadband metamaterial absorber operating in the GHz range. The proposed structure consists of three layers: a periodic square-shaped array made of molybdenum disulfide (MoS2) on the top, a continuous polyimide layer in the middle and a continuous...
Metamaterial full-sized absorber structures are numerically and experimentally investigated in GHz region and then examined in THz frequency. By manipulating monitoring the number and the position of the defect elements in conventional unit cells, the op

2. Design and method Based on the reference literature[15], we determined that the absorber in our design adopts a square pillar structure. To achieve broadband absorption, we designed the graphene pattern on the top of the absorber as four triangular shapes, forming multiple resonant structures....
A simple design of terahertz metamaterial absorber (MA) based on a periodic array of square copper films was investigated numerically. The perfect narrow absorption mainly originates from magnetic polariton excitation and perfect impedance-match. The perfect absorbing properties of this simple design coul...
