Abstract
Knowledge of the radiation transfer through porous materials is important for a variety of engineering systems. In our experiments with layers of packed microparticles on metal, the fraction of light that is directed from normal incidence into waveguided modes is non-negligible; we seek to estimate the absorption in this porous layer with a few, simple experiments. We employ a ray transfer-function approach and provide analytic relations for the reflected, waveguided, and transmitted light. With these relations and multi-modal experimental data taken at different laser wavelengths, the interplay between reflection, waveguiding, and transmission can be estimated. We find that waveguiding is significant when the single-pass absorption of a porous slab is more than a few percent.
期刊介绍:
Rapid progress in optics and photonics has broadened its application enormously into many branches, including information and communication technology, security, sensing, bio- and medical sciences, healthcare and chemistry.
Recent achievements in other sciences have allowed continual discovery of new natural mysteries and formulation of challenging goals for optics that require further development of modern concepts and running fundamental research.
The Journal of the European Optical Society – Rapid Publications (JEOS:RP) aims to tackle all of the aforementioned points in the form of prompt, scientific, high-quality communications that report on the latest findings. It presents emerging technologies and outlining strategic goals in optics and photonics.
The journal covers both fundamental and applied topics, including but not limited to:
Classical and quantum optics
Light/matter interaction
Optical communication
Micro- and nanooptics
Nonlinear optical phenomena
Optical materials
Optical metrology
Optical spectroscopy
Colour research
Nano and metamaterials
Modern photonics technology
Optical engineering, design and instrumentation
Optical applications in bio-physics and medicine
Interdisciplinary fields using photonics, such as in energy, climate change and cultural heritage
The journal aims to provide readers with recent and important achievements in optics/photonics and, as its name suggests, it strives for the shortest possible publication time.
