W BAND IMAGING SYSTEM USING LINEAR SPARSE PERIODIC ANTENNA ARRAY AND COMPRESSIVE SENSING FOR PERSONNEL SCREENING

This paper presents our study on a W band imaging system consisting of a linear sparse periodic antenna array (SPA) with only 10 transmitting (Tx) and 10 receiving (Rx) elements in simulation Womens Sweater and experiment for the purpose of personnel screening.We have devised a simplified and low cost experimental set-up using only 1 Tx and 1 Rx ch

Fused SIBERIAN GINSENG silica with surface structures has potential applications in microfluidic, aerospace and other fields.To fabricate structures with high dimensional accuracy and surface quality is of paramount importance.However, it is indeed a challenge to strike a balance between accuracy and efficiency at the same time.Here, a temporally s
