Lightning Responses on a Finite Cylindrical Enclosure
The voltage on a single-turn loop inside an enclosure characterizes the enclosure shielding effectiveness against a lightning insult. In this paper, the maximum induced voltage on a single-turn loop inside an enclosure from lightning coupling to a metal enclosure wall is expressed in terms of two multiplicative factors: (A) the normalized enclosure wall peak penetration ratio (i.e., ratio of th...
متن کاملVibroacoustic study of circular cylindrical tubes in roller coaster rails
Excessive noise generated by roller coasters during operation is a significant issue for amusement parks located near residential and business districts. Previous work showed that filling the rails with sand and pea gravel can provide noise reduction levels of up to 10 and 15 decibels. However, using damping materials may require additional support structures to accommodate the weight increase ...
متن کاملCOUPLING AND POWER DISSIPATION IN A COAXIALLY EXCITED TM01l MODE CYLINDRICAL APPLICATOR WITH A SPHERICAL LOAD
This paper presents the results of 3D FDTD modeling of a 915-MHz cylindrical structure with the TM01l mode excited by a coaxial line and intended for thermal processing of a spherical load (a fruit). Energy coupling is shown to be insensitive to the fruit’s type and temperature, but dependent on its size and location and the loop’s radius. The patterns of dissipated power are analyzed from the ...
متن کاملUltra Wideband Monopole Antenna Excited by a Capacitive Coupling Feed with Double Band Notch Function
This paper presents the results of a new monopole antenna that exhibits 2.75-10.7 GHz performance. The proposed antenna consists of a radiating patch with notches excited by capacitive coupling feed. Also, the antennas truncated ground-plane incorporates a central notch. This modification significantly improves the antennas impedance bandwidth by 118% over an ultra-wideband frequency range. T...
متن کاملCharacteristics of Electromagnetic Coupling with A Wire Through Enclosure
Electromagnetic interference can be easily coupled into metallic shielding enclosure that is penetrated with a conducting wire, which having a harmful effect on electrical and electronic devices. To sudy the characteristics, Finite Difference Time Domain (FDTD) is applied in both frequency and time domain for modeling the coupling of an incident electromagnetic pulse (EMP) with a conducting wir...
