Example: (diode OR solid-state) AND laser [search contains "diode" or "solid-state" and laser], Example: (photons AND downconversion) - pump [search contains both "photons" and "downconversion" but not "pump"]. The equation T + R + A = 1describes the theory, where T=transmittance, R=reflectance, and A=absorptance. 0000003800 00000 n Separate search groups with parentheses and Booleans. Bortchagovsky Institute of Semiconductor Physics of National Academy of Sciences of Ukraine, pr. Providing support for the notion that rays provide the “skeleton” of electromagnetic waves, we perform a Fourier transform of the (experimentally measurable) solar cell reflection amplitude, which reveals the rays as peaks in the optical path length spectrum. or . xref 0000004504 00000 n 0000005988 00000 n 0000008608 00000 n Shows that ray simulations are accurate only if phases are associated with each ray. 0000001094 00000 n The basic formulas which are utilized in the calculations are given together with the essential details of the machine program, including a macro-flow diagram. Thin films are used commercially in anti-reflection coatings, mirrors, and optical filters. Reflectance at wavelengths from 200 nm to 2000 nm may be calculated. The theory is briefly explained in the following section, which is based on matching the boundary conditions Click here to learn more. 0000000016 00000 n This have so far not been treated in the quantum ray-splitting literature. startxref A general program for the IBM 650 is presented for calculating the reflectance and transmittance of arbitrary multilayer combinations of absorbing and nonabsorbing films as functions of wavelength and angle of incidence. You may subscribe either as an OSA member, or as an authorized user of your institution. There is a profound duality between rays and waves. . Use quotation marks " " around specific phrases where you want the entire phrase only. Soc. Presents an exact ray solution of the 1D Helmholtz equation with a complex refractive index as a model for thin solar cells. Note the Boolean sign must be in upper-case. You do not have subscription access to this journal. An application of our exact ray theory to a silicon solar cell is also provided. Soc. Learn more about our response to COVID-19 including information for. At normal incidence they can recalculate the expression for reflectance R. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored. 0000001886 00000 n ]yE^$��K�"%������p�\Ǐn?696�8~̜��Q��4ǦY��ȋ�R����m``�``26v� ���AL�I*�2J@�0��Y��Sb`��%-�j% {:�-c�e��Af!�yL��:�&1=c�ɘ�����0���4F.F��n�����.0r1�eH`Ta8����h�VF�K��@�0`��2� �b��u � �:@� �zr� If it is assumed that the supplementary polarization at the surface is small compared with Thin film calculator is a program which is embedded in OptiScan which can be used to calculate the amplitude reflection and transmission coefficients, phase change, reflectance and transmittance of both s and p polarized light. Reflectance Calculator. Improve efficiency in your search by using wildcards.

Treating the one-dimensional case exactly, our paper lays the foundation for constructing exact ray theories for application to solar cell absorption cross section in two and three dimensions. J. Opt. You may subscribe either as an OSA member, or as an authorized user of your institution. For best results, use the separate Authors field to search for author names. These films are created through deposition processes in which material is added to a substrate in a controlled manner.

Berning, "Thin Films Calculations Using the IBM 650 Electronic Calculator," J. Opt. The total contribution ρ of all of the rays of our subclass to the total reflection amplitude r is (D.1) ρ = ∑ p = 0 ∞ ∑ q = 0 ∞ p + q p t 1 2 t 2 2 p + 2 r 1 p r 2 q e i k [2 (p + 1) n 1 a 1 + 2 (p + q + 1) n 2 a 2], where t 1 and r 1 are transmission amplitude and right-reflection amplitude at the vacuum/film interface, t 2 and r 2 are transmission amplitude and right-reflection amplitude at the film/film interface, a 1 is the …
