The aim of the present study was to control entanglements in order to regulate the properties of polymeric solids. Initially, fabrication of polymeric solids with few entanglements was attempted. Films of the DNA–cationic surfactant, cetyltrimethyl

A ten-element imaging array which consists of an integrated antenna-detector system that incorporates trap-loaded Yagi antennas and Schottky diodes has been developed for operation in the millimeter-wave band around 70 GHz. Also, a prototype optical

A millimeter-wave imaging array is proposed in which many Yagi-Uda antennas are placed on a dielectric lens. By changing the dimensions of these antennas, the impedance matching with the detector is optimized. At the same time, a radiation pattern ma

A millimeter‐wave phase‐imaging interferometer has been developed for the study of density profiles of the GAMMA 10 tandem mirror. The interferometer uses a 70‐GHz klystron oscillator and a quasi‐optical transmission system. The probe beam is

An imaging array consisting of five Yagi-Uda antennas in a dielectric has been constructed for 50 GHz that has antenna patterns suitable for millimetre-wave applications. Crosstalk levels of less than −30 dB between adjacent antennas in an f/1.0 im
