Abstract.
We examine the utility of Light-Emitting Diodes (LEDs) for short-range intersatellite links (ISLs), and compare and contrast LEDs with existing laser technologies used for long-distance ISLs. A hypothetical low-end LED ISL page link is described, and applications are suggested

the new world of Plasma Antennas



Antenna technology

Physically, an antenna is an arrangement
of one or more conductors, usually
called elements. In transmission,
an alternating current is created in the
elements by applying a voltage at the
antenna terminals, causing the elements
to radiate an electromagnetic field. In
reception, the inverse occurs. An electromagnetic
field from another source
induces an alternating current in the elements
and a corresponding voltage at

POLYMER LIGHT EMITTING DIODES (PLEDs)

Polymer LED (light-emitting diode) - sometimes called light-emitting polymer or polyLED - is a technology based on the use of polymer as the semiconductor material in LEDs.

Polymers are chemical substances that consist of large molecules that are themselves, made from many smaller and simpler molecules.

Polymers are largely identified with insulation.

Research institutes have come up with ideas to integrate polymers into main stream electronics as it has been established that certain poly ....etc

liquid-crystal displays (LCDs)



INTRODUCTION

LED-based moving-message displays are becoming popular for transmitting information to large groups of people quickly. These can be used indoors or outdoors. We can find such displays in areas like railway platforms, banks, public offices, hotels, training institutes, nightclubs and shops.
Compared to LEDs, liquid-crystal displays (LCDs) are easy to interface with a microcontroller for displaying information as these have many ....etc

Synergistic Effects of Surfactants

Observed when surfactants having relatively similar structure or ionic property are mixed
Resulted in the formation of liquid crystal structures or complexes at the interface by intermolecular interactions between surfactants
Examples
Anionic and nonionic in synthetic latex emulsion polymerisation,

Definition
Scientific research in the area of semiconducting organic materials as the active substance in light emitting diodes (LEDs) has increased immensely during the last four decades. Organic semiconductors was first reported in the 60:s and then the materials where only considered to be merely a scientific curiosity. (They are named organic because they consist primarily of carbon, hydrogen and oxygen.). However when it was recognized in the eighties that many of them are photoconductive under visible light, industrial interests were att ....etc

Abstract:
reflective cholesteric liquid crystal displays (Ch-LCDs) because they are lightweight, low power flat-panel displays. Furthermore, Ch-LCDs can be made bistable which allows for the manufacture of large area, high- resolution displays without the need for expensive, difficult to manufacture active matrix addressing schemes. Also, the bistability enables flicker-free operation. Currently, these displays are made using glass substrates. However, some applications require rugged (i.e., nonbreakable), flexible displays. The use of a plas ....etc
