Abstract¬—The protection against electromagnetic environment effects (E3) on system is becoming more important since the modern communication based on wireless technology is developing fast. The reduction of the electromagnetic interference(EMI)and ensuring compatibility for communication systems are included in this topic, and principally data links protection and terminals against the lightning and high-power electromagnetic pulse(HEMP)to obtain the normal operation of these sort of systems. The focus of this paper is on E3 analysis, designing and operating for protecting the electronic equipment and communication network system and its worthwhile in ensuring effective performing that mission in the complex of electromagnetic today (EME).
Key Words: electromagnetic environments (EME), electromagnetic environmental effects (E3), electromagnetic compatibility (EMC), high-power electromagnetic pulse (HEMP), communication systems.

1. Introduction

Today, the world is experiencing a revolution in information and becoming more and more dependent on electromagnetic performance. The universal reliance of electronics and electromagnetism civilian system or military instruments, besides in mission and safety-critical as applications of fundamental importance, brings the issue of protection versus electromagnetic environment effects(E3) into focus. The susceptibility of communication systems is either because of special interest or of information technology equipment (ITE) depending on access to the electromagnetic (EM)spectrum information processing or control functions, since this is easy to get involved with but hard to protect. The impact of electromagnetic interference (EMI)is caused by deliberating vulnerability, accidental

As the World Trade Center lay in ruins, also destroyed were a vast array of communication equipment from transmission antennae for radio and TV stations to switching equipment for phone service. Though throughout all this people were still able to communicate, TV and radio stations were still transmitting their signal. Much of this was a result of wireless and satellite technology.…

    The question now how deep electromagnetic waves penetrate into the ground and the resolution as a function of depth is of prime importance in EM surveying. In an isotropic resistive medium, EM waves would travel virtually indefinitely. However, in the real world, where surface conductivities are significant, the depth of penetration is often very limited. Theoretically, the maximum penetration depth at which an EM plane wave has been attenuated to e-1 (or 37%) relative to its initial amplitude in a fairly conductive homogeneous half-space and results in magnetic and electric field components that are detectable by an VLF–EM equipment at a particular operating frequency, is known as skin-depth 'δ'…

    Various schematic symbols and diagrams are familiarized and a schematic is a collection of electronic symbols connected together with virtual “wires”. When fabricating a printed circuit board (PCB), a schematic is needed to provide input (a netlist) to the layout and routing tool (Varteresian, 2002)[1]. In other words, the capture of a schematic diagram is a convention to PCB, subsequent construction and testing. The design of PCBs is very widely used in electronic equipment and systems, for example, good EMC (Electromagnetic Compatibility) practices. These PCB-level EMC practices usually help achieve the required EMC performance at a much lower cost than alternative EMC measures at higher levels of integration, such as whole-product shielding. They also improve signal integrity in both analogue and digital circuits (Armstrong, Aug 1999)(Journal 1). Power decoupling techniques can improve the power supply of a PCB and transmission lines techniques are a part of the PCB layout (Armstrong, Oct 1999) (Journal 2). The MM232R is a miniature development module which uses FTDI’s FT232RQ. In this assignment, MM232R needed to be designed according to the datasheet. Besides, switches of four pins also needed to be designed, but only two pins were used in diagram. PIC18F1320, a microcontroller, which features six enhanced power-managed “software controlled” modes, power consumption as low as 0.1 microamps in standby mode and a wide operating voltage range from 2 to 5.5 volts which makes this device ideal for battery managed applications (Unknown, 2007)[2]. It has some advantages, such as namely and high computational performance at an economical price, with the addition of high endurance Enhanced Flash program memory. There are a range of features that can…

    Electromagnetic compatibility (EMC) has been around since the early 1950s, predominantly regarding the motorised noise conducted over the power lines to sensitive equipments. [1] With the advancement of digital circuits, the switching speeds of equipments have increased dramatically. Since electromagnetic interference is caused by the changes in current with respect to time, the increase of switching frequency will cause false logic switching and improper operation of devices. [1] Wireless technologies and congestions of communication bands have also contribute to the awareness towards electromagnetic compatibility. [3]…
