Radiation from the Open End of a Coaxial Cable
نویسندگان
چکیده
(1) and c is the speed of light in vacuum. Estimate the time-average power P (i.e., the radiation) that escapes from the end of the cable using vector (or scalar) Huygens-Kirchhoff diffraction theory for the case that the cable is excited with a TEM wave with λ b. Compare the cases of a coaxial cable by itself, and one with its outer conductor attached to a ground plane such that the radiation is into a half space. You may assume that the medium outside the cable has unit relative permittivity and unit relative permeability.

Study of a Hybrid - Analog TV and Ethernet- Home Data Link using a Coaxial Cable
The paper presents an implementation and compatibility tests of a simple home network implemented in a nonconventional manner using a CATV coaxial cable. Reusing the cable, normally designated to supply RF modulated TV signals from cable TV networks, makes possible to add data services as well. A short presentation of the technology is given with an investigation of the main performances obtain...
متن کاملSupporting Quality of Service in the Head - End of Hybrid Fiber - Coaxial Networks
Many cable operators have begun the process of upgrading their cable systems in anticipation of delivering a wide range of interactive digital services to the home. These newer hybrid fiber-coaxial (HFC) networks can take advantage of unused bandwidth in broadcast cable television (CATV) and allow for an inexpensive and simple way for home users to have access to many broadband digital applicat...
متن کاملTwo-slot coiled coaxial cable resonator: reaching critical coupling at a reduced number of coils.
This paper reports the experimental demonstration of a coiled coaxial cable resonator capable of meeting the critical coupling condition using a reduced number of coils relative to previously reported coiled resonators. By introducing a second slot along the length of the device, a two-slot coiled coaxial cable resonator was fabricated and critical coupling observed at 22 turns. An additional d...

Planning robot trajectory is a complex task that plays a significant role in design and application of robots in task space. The problem is formulated as a trajectory optimization problem which is fundamentally a constrained nonlinear optimization problem. Open-loop optimal control method is proposed as an approach for trajectory optimization of cable parallel manipulator for a given two-end-po...
متن کاملEffects of Length and Diameter of Open-Ended Coaxial Sensor on its Reflection Coefficient
This paper presents a calibration technique for a coaxial sensor using a transmission signal approach. The sensor was fabricated from commercially available RG402/U and RG405/U semi-rigid coaxial cable. The length of the coaxial sensor was correlated with the attenuation and standing wave inside the coaxial line. The functions of multiple reflection amplitude and tolerance length with respect t...
