Circumstellar Material in Young Stellar Objects
... One of the basic tasks of science is to understand how we and the world around us have come into existence. The thesis presented here deals with a small part of that question: how do stars form? In the eighteenth century the French astronomer Laplace asked himself the same question, and came up with ...

Introduction to Diffraction Grating
... occurs is the blaze wavelength. Holographic gratings are generally less efficient than ruled gratings because they cannot be blazed in the classical sense. There are also special cases (e.g. when the spacing to wavelength ratio is near one) where a sinusoidal grating has virtually the same efficienc ...

Principles of Fiber Optic Communication
... Communication implies transfer of information from one point to another. When it is necessary to transmit information, such as speech, images, or data, over a distance, one generally uses the concept of carrier wave communication. In such a system, the information to be sent modulates an electromagn ...
