Introduction,aves, which include those in optics, are governed by Maxwell’s equations. The main reason for this was the absence of coherent optical sources equivalent to klystrons or magnetrons for microwaves, or oscillators for lower frequencies. However, the invention of the laser has changed this situation anconstruct 发表于 2025-3-24 02:46:56
Optics Fundamentals,ent at 60Hz, radio waves, microwaves, infrared, X-rays and γ-rays. Electromagnetic waves obey Maxwell’s equations, which are introduced in Sect. 2.1, which also treats the electromagnetic wave equation followed by the plane-wave solution in homogeneous, linear isotropic space. This is followed by th同来核对 发表于 2025-3-24 06:33:07

Optics Fundamentals, geometrical optics is reviewed first and a discussion of lens aberration is included. The matrix method is then extended to introduce gradient optical fibers. The subjects of step-index fibers and integrated optics are tackled together in Sect. 2.11. Sections 2.12–16 deal with anisotropic media, in全等 发表于 2025-3-25 00:17:07
