Infrared Physics & Technology, 2006
Abstract This paper presents a method to manufacture a low loss window applicable for THz frequencies. The window is made out of high resistivity silicon (3 kΩ cm, n = 3.42, and α = 0.1/cm). Reflective loss due to the impedance mismatch between the substrate and free space is overcome by etching (Bosch-process) rectangular grooves of depth λ /4 ...

1998 Symposium on Antenna Technology and Applied Electromagnetics, 1998
Microstrip antenna arrays, in space applications, are relatively new, and have not reached to the level of utilization as the reflector antennas and slotted waveguide arrays. Two areas they need improvement, the design accuracy and substrate quality.

Low-Loss Waveguide Transmission
Proceedings of the IRE, 1953The circular electric mode in round metallic tubing becomes increasingly more attractive than the dominant mode from the standpoint of minimzing the waveguide size at frequencies above about 10,000 mc for the loss criterion of 0.25 db/100 feet. The circular electric (TE01) mode also makes available a theoretical heat loss of 2 db/mile in waveguides ...

Low Loss Dielectric Waveguides
IEEE Transactions on Microwave Theory and Techniques, 1954The history of dielectric waveguides begins back in 1910 with the publication of a theoretical paper by Hondros and Debye, who gave a mathematical treatment of transverse magnetic mode propagation in lossless dielectric guide. In the 1930's Southworth began experimental work on these modes while Carson, Mead, and Schelkunoff developed a general theory ...

IEEE Journal of Oceanic Engineering, 2005
The shallow refracted path through sea floor sediments plays a significant role in the transmission of acoustic energy at low frequencies. For bottom grazing angles of 90/spl deg/ to 25/spl deg/, low-frequency acoustic energy was observed to come from reflected paths.
