The method uses scattering parameters of a material sample embedded in a waveguide, namely and , to calculate permittivity and permeability data. and correspond to the cumulative reflection and transmission coefficient of the sample that are referenced to the each sample end, respectively: these parameters account for the multiple internal reflections inside the sample, which is considered to ...
Reflective writing helps students to develop a better understanding of their goals. Reflective writing is regularly used in academic settings, as it helps students think about how they think and allows students to think beyond the scope of the literal meaning of their writing or thinking. [8] In other words, it is a form of metacognition ...
A reflective essay is an analytical piece of writing in which the writer describes a real or imaginary scene, event, interaction, passing thought, memory, or form—adding a personal reflection on the meaning of the topic in the author's life. Thus, the focus is not merely descriptive.
The decadic absorbance of a scattering sample is defined as −log 10 (R+T) or −log 10 (1−A). For a non scattering sample, R = 0, and the expression becomes −log 10 T or log( 1 / T ), which is more familiar. In a non-scattering sample, the absorbance has the property that the numerical value is proportional to sample thickness.
Diode-array spectrophotometers differed from the original spectrophotometer created by Beckman because it was the first single-beam microprocessor-controlled spectrophotometer that scanned multiple wavelengths at a time in seconds. It irradiates the sample with polychromatic light which the sample absorbs depending on its properties.
Reflection of light is either specular (mirror-like) or diffuse (retaining the energy, but losing the image) depending on the nature of the interface.In specular reflection the phase of the reflected waves depends on the choice of the origin of coordinates, but the relative phase between s and p (TE and TM) polarizations is fixed by the properties of the media and of the interface between them.

The cognitive reflection test (CRT) is a task designed to measure a person's tendency to override an incorrect "gut" response and engage in further reflection to find a correct answer. However, the validity of the assessment as a measure of "cognitive reflection" or "intuitive thinking" is under question. [ 1 ]
