Field coupling to nonuniform transmission lines with linear characteristic impedance
Tập 2 - Trang 621-626 vol.2
In this paper, plane wave field-coupling onto a nonuniform, lossless,
transmission line running over a ground plane is solved analytically by means of
a power series expansion in the longitudinal variable z. A linear variation of
the characteristic impedance versus z is assumed. It is shown via examples that
the obtained analytical results represent the limit solution of the approach
based on the ...

Noise coupling to on-chip integrated antennas
Tập 1 - Trang 340-344 vol.1
Noise from digital circuits can couple to on-chip integrated antennas and
degrade the received signal-to-noise ratio. To investigate coupling mechanisms,
integrated antennas and noise generating circuits were fabricated in 0.25 /spl
mu/m and 0.1 /spl mu/m CMOS processes. Noise coupling through the substrate is
found to be common-mode in nature. Signals on long interconnects near antennas,
as well ...

Co-channel interference modeling of the ANSI/TIA/EIA-95-B code division multiple access cellular system
Tập 2 - Trang 826-829 vol.2
Spectral efficiency is an essential component of existing and new technologies
in personal communications services (PCS). The growing demand for PCS has
resulted in an increasingly crowded spectrum. Code division multiple access is
one of the best methods for efficient use of the radio spectrum. Code division
is used in some second generation PCS systems and is used or proposed for all
third gener...

Comparison of magnetic fields emitted from security screening devices with magnetic field immunity standards
Tập 2 - Trang 937-940 vol.2
The Food and Drug Administration (FDA) received over 90 problem reports of
medical device malfunctions due to electromagnetic interference (EMI) from
magnetic field emitting security devices. The FDA took action to alert users and
manufacturers of medical devices and security screening devices. These
malfunctions were thought to be related to the electromagnetic fields emitted
from the security de...

Analysis of signal propagation in high-speed differential signal lines with full-wave time-domain technique
Tập 2 - Trang 1004-1009 vol.2
With the advancements in electronics, interests in interconnect of high-speed
digital circuits and IC packaging have greatly increased in EMC community for
signal integrity (SI). However, in order to take complex electromagnetic effects
such as radiation, reflection and coupling into account, full-wave numerical
techniques must be resorted, which usually result in intensive computation. This
paper...

Shielding effectiveness of vent holes-TLM modeling validation
Tập 2 - Trang 721-726 vol.2
The use of modelling software for electromagnetic interference (EMI) evaluation
allows for a significant advantage in design. Software modeling tools come in a
variety of computational methods, with one of these options being the
transmission line matrix (TLM) method A formal validation of this method is
performed by comparing simulation results to the empirical data of a vented
enclosure. This va...

Tác động tải của EUT đến mức điện trường tối đa trong phòng cộng hưởng cho kiểm tra miễn nhiễm Dịch bởi AI
Tập 2 - Trang 972-975 vol.2
Trong một thử nghiệm miễn nhiễm EMC, điện trường tối đa do cơ sở thử nghiệm tạo
ra gây ra nhiều mối quan tâm. Bài báo này trình bày một kỹ thuật để đánh giá tác
động tải của EUT (thiết bị thử nghiệm) lên mức điện trường tối đa trong một
phòng cộng hưởng. Ảnh hưởng của EUT được nghiên cứu với các độ dẫn điện khác
nhau. Từ các kết quả, có thể thấy rằng EUT có thể gây tải mạnh lên phòng cộng
hưởng kh...

More on field perturbations due to accessories used in radiated emissions tests
Tập 2 - Trang 605-610 vol.2
Normalized site attenuation (NSA) measurements are taken in the absence of
necessary accessories, such as the 80 cm-high table on which test samples must
be supported We presented a paper at the 2001 IEEE EMC Symposium, documenting
measurement anomalies that come from field distortions caused by test
accessories. This paper reports on additional work in this area. The paper
updates our proposed te...
