	abstract = {In this work we review the use of spherical modes in computational electromagnetics mainly applied to antenna problems. First, the theory of spherical modes will be reviewed. Second, the use jointly with the Finite Element Method will be exposed. Third, the application to the analysis of finite arrays will be shown. Finally, it will be presented how the spherical modes allow us to obtain an equivalent model of the antenna, in terms of infinitesimal dipoles, which increases the capabilities of the method for the analysis of finite arrays.},

	abstract = {A waveguide circular polarizer with reconfigurable polarization sense is proposed in this paper. The polarizer can be switched between right and left hand circular polarization. The polarization sense is controlled by RF MEMS switches, which commute between two states for allowing or blocking adequately two different signal paths inside the waveguide structure. The polarizer is made up of three building blocks, involving E-plane waveguide MEMS SP2T switch, ridge to waveguide transitions and a septum-orthomode transducer. A switchable Ku-band polarizer prototype is designed and tested as a proof of concept. The experimental performance shows acceptable return losses and axial ratio levels in the 12.7 to 14.8 GHz band (15.3\% fractional bandwidth). The proposed structure is compact and is useful for applications that require fast polarization switching.},
