Plane-wave scattering by a dielectric circular cylinder
... Recently, we studied the scattering problem of a plane wave by a perfectly conducting circular infinite cylinder placed in front of a plane discontinuity for the electromagnetic constants. The proposed method, starting from the customary expansion of the scattered field, exploits the plane-wave repr ...

Mach Zehnder Interferometer and its Applications
... with a minute lateral offset as shown in fig.5 (b). Due to this offset, a part of the beam in core is coupled to several cladding modes, independent of wavelength. An MZI can also be formed by fusion splicing a piece of Photonic Crystal Fiber (PCF) in between fibers with a small required deviation [ ...

... and then using a ~150 µm long adiabatic inverse-taper to couple the field into active layers [4]. This method relaxes the tolerance of sharp InP-based active layers tip width to ~500nm [4], but the disadvantage is in the form of an extra step of lithography and etching for realizing two-step coupler ...

TAP 313 - 1: Polarisation of waves
... This seems to be contradictory behaviour compared to the ‘mechanical filter’. When the grill is parallel to the direction of polarisation, the free electrons in the metal are accelerated by the electric field in the em wave, thus absorbing energy from the wave. The energy is re-radiated in all direc ...

Hence, at optical frequencies an antenna no longer responds to the external wavelength but to a shorter effec ...
