c able television (CATV) was known originally as "community antenna television." Today it represents the broad area of entertainment and other services carried over coaxial cable networks to various subscribers, As implied by the name, the original purpose of CATV was to serve communities with entertainment television service where TV reception was poor, The idea was to find one good receiving ...

Introduction: Interconnection problems between large number of coil elements and the scanner are critical, particularly in high field MRI. Moreover, SNR and RF safety issues are also significant concerns. Recent investigations on the analog optical transmission of MRI signals may alleviate this problem [1-3]. Although traditionally, the transmission of the MR signals is achieved by coaxial cabl...

Allocation and Scheduling Algorithms for IEEE 802.14 and MCNS in Hybrid Fiber Coaxial Networks Ying-Dar Lin Chen-Yu Huang Wei-Ming Yin Abstract|IEEE 802.14 and MCNS are two standards developed for the Hybrid Fiber Coaxial (HFC) CATV networks. Both standards model an upstream channel as a stream of minislots. But their philosophies on resolving collisions in the shared upstream channel are rathe...

Abstract—A printed Log-periodic dipole array (LPDA) is presented, operating over the C, X and Ku bands. The antenna feeding structure consists of two coaxial cables, in order to realize an infinite balun which provides the required broadband input matching. The second coaxial cable mirrors the first one, connected to the antenna input, and is capable of both stabilizing the antenna phase center...

This paper presents the electromagnetic Finite Element Analysis (FEA) of a novel chip-to-chip interconnect for use in System-in-Package (SiP) applications. An on-chip coplanar transmission line is transitioned to an off-chip coaxial cable using an etched trench on Silicon. This approach to die-to-die signaling has inherent advantages over traditional wire bonding that include matched impedance,...

Quantum graphs provide a setting to test the hypothesis that all ray-chaotic systems show universal wave chaotic properties. Here, an experimental setup consisting of a microwave coaxial cable network is used to simulate quantum graphs. The networks which are large compared to the wavelength, are constructed from coaxial cables connected by T junctions. The distributions of impedance statistics...

Recently, the demand on position detection system using WiFi[1] and cellular phone[2] have been appeared. Car navigation system and 3G cellular phone use GPS(Global Positioning System) for position detection. However, it is impossible to use GPS underground because GPS signal cannot be received due to obstacles. Therefore, many position detection methods to use at narrow area have been proposed...
