Reflection of electromagnetic waves from mixtures of plane gravitational and scalar waves [PDF]
, 2006 We consider colliding wave packets consisting of hybrid mixtures of electromagnetic, gravitational and scalar waves. Irrespective of the scalar field, the electromagnetic wave still reflects from the gravitational wave.

Characterization of Gas Absorption Modules Based on Flexible Mid-Infrared Hollow Waveguides
Sensors, 2019 A new gas absorption module, the substrate-embedded hollow waveguide (eHWG) model, is proposed. It consists of a substrate with a curved channel and a hollow waveguide. The hollow waveguide is curved into the channel and works as a gas absorption cell as

Electromagnetic waves destabilized by runaway electrons in near-critical electric fields [PDF]
, 2013 Runaway electron distributions are strongly anisotropic in velocity space. This anisotropy is a source of free energy that may destabilize electromagnetic waves through a resonant interaction between the waves and the energetic electrons. In this work we
