  order modes
Rectangular-waveguide devices intended for the withdrawal and absorption of high-order modes (HOMs) from the superstructure of the TESLA linear electron-positron collider are investigated.
      
It is shown that, unlike the lowest order mode, the higher order modes, which primarily depend on the curvature of the boundary, demonstrate a weak nonreciprocity of propagation in directions with opposite azimuths.
      
Their spatial distributions correspond to simultaneous cross-modulation self-locking of its first-and higher-order modes into the common nonlinear waveguide formed by them.
      
Higher-order modes are considered systematically using the separation of variables method.
      
It is found that an asymmetric position of the active region in an ultrawide waveguide reduces the optical confinement factor for higher-order modes and raises the threshold electron density for these modes by 10-20%.

The effects of sample dimensions, surface recombination velocity and the ponetrati- ng length of the illuminating light on the high order modes in photoconductive decay of excess carriers in semiconductor have been studied. It was found that the role of the high order modes can be considerably minimized by using penetrating light, sample of large size and low surface recombination velocity. The bulk lifetime of the filament can than be more accurately determined.

In orthogonally polarized H(11)° Multi-mode circular waveguide systems,filtration of several lower high-order modes such as E(01)° E(11)° has been treated favorably. However, no report on further research in the filtration of higher-order modes such as H(21)° has so far been revealed. In this paper, operational principle and design scheme of an H(21)° mode filter are dealt with, approximate formula for determining mode coupling quantities according to Bethe's small Holes diffraction theorems is derived, and methods for compu-ting mode attenuations for cascaded multicavity filter and reflection characteristics of dominant mode are proposed. Experimental results have checked well with the theoretical analysis and design formulas; the transmission characteristics of the dominant and higher-order modes are perfectly satisfactory.

The transverse mode discrimination of waveguide laser resonator has been discussed and some valuable results have been obtained. It is notable that systematic analyses of problems mentioned above have not been seen in the present literatures
